 ## Introduction

-**GreptimeDB** is an open-source, cloud-native database that unifies metrics, logs, and traces, enabling real-time observability at any scale — across edge, cloud, and hybrid environments.
+**GreptimeDB** is an open-source unified & cost-effective time-series database for **Metrics**, **Logs**, and **Events** (also **Traces** in plan). You can gain real-time insights from Edge to Cloud at Any Scale.

-## Features
+## Why GreptimeDB

-|   Feature  | Description |
-| --------- | ----------- |
-| [All-in-One Observability](https://docs.greptime.com/user-guide/concepts/why-greptimedb) | OpenTelemetry-native platform unifying metrics, logs, and traces. Query via [SQL](https://docs.greptime.com/user-guide/query-data/sql), [PromQL](https://docs.greptime.com/user-guide/query-data/promql), and [Flow](https://docs.greptime.com/user-guide/flow-computation/overview). |
-| [High Performance](https://docs.greptime.com/user-guide/manage-data/data-index) | Written in Rust with [rich indexing](https://docs.greptime.com/user-guide/manage-data/data-index) (inverted, fulltext, skipping, vector), delivering sub-second responses at PB scale. |
-| [Cost Efficiency](https://docs.greptime.com/user-guide/concepts/architecture) | 50x lower operational and storage costs with compute-storage separation and native object storage (S3, Azure Blob, etc.). |
-| [Cloud-Native & Scalable](https://docs.greptime.com/user-guide/deployments-administration/deploy-on-kubernetes/greptimedb-operator-management) | Purpose-built for [Kubernetes](https://docs.greptime.com/user-guide/deployments-administration/deploy-on-kubernetes/greptimedb-operator-management) with unlimited cross-cloud scaling, handling hundreds of thousands of concurrent requests. |
-| [Developer-Friendly](https://docs.greptime.com/user-guide/protocols/overview) | SQL/PromQL interfaces, built-in web dashboard, REST API, MySQL/PostgreSQL protocol compatibility, and native [OpenTelemetry](https://docs.greptime.com/user-guide/ingest-data/for-observability/opentelemetry/) support. |
-| [Flexible Deployment](https://docs.greptime.com/user-guide/deployments-administration/overview) | Deploy anywhere from ARM-based edge devices (including [Android](https://docs.greptime.com/user-guide/deployments-administration/run-on-android)) to cloud, with unified APIs and efficient data sync. |
+Our core developers have been building time-series data platforms for years. Based on our best practices, GreptimeDB was born to give you:

-  ✅ **Perfect for:**
-  - Unified observability stack replacing Prometheus + Loki + Tempo
-  - Large-scale metrics with high cardinality (millions to billions of time series)
-  - Large-scale observability platform requiring cost efficiency and scalability
-  - IoT and edge computing with resource and bandwidth constraints
+* **Unified Processing of Metrics, Logs, and Events**

-Learn more in [Why GreptimeDB](https://docs.greptime.com/user-guide/concepts/why-greptimedb) and [Observability 2.0 and the Database for It](https://greptime.com/blogs/2025-04-25-greptimedb-observability2-new-database).
+  GreptimeDB unifies time series data processing by treating all data - whether metrics, logs, or events - as timestamped events with context. Users can analyze this data using either [SQL](https://docs.greptime.com/user-guide/query-data/sql) or [PromQL](https://docs.greptime.com/user-guide/query-data/promql) and leverage stream processing ([Flow](https://docs.greptime.com/user-guide/flow-computation/overview)) to enable continuous aggregation.

-### Memory profiling for greptimedb docker image
-
-We have memory profiling enabled and activated by default in our official docker
-image.
-
-This behavior is controlled by configuration `enable_heap_profiling`:
-
-```toml
-[memory]
-# Whether to enable heap profiling activation during startup.
-# Default is true.
-enable_heap_profiling = true
-```
-
-To disable memory profiling, set `enable_heap_profiling` to `false`.
-
-### Memory profiling control
-
-You can control heap profiling activation using the new HTTP APIs:
-
-```bash
-# Check current profiling status
-curl -X GET localhost:4000/debug/prof/mem/status
-
-# Activate heap profiling (if not already active)
-curl -X POST localhost:4000/debug/prof/mem/activate

-# Deactivate heap profiling
-curl -X POST localhost:4000/debug/prof/mem/deactivate

-# Activate gdump feature that dumps memory profiling data every time virtual memory usage exceeds previous maximum value.
-curl -X POST localhost:4000/debug/prof/mem/gdump -d 'activate=true'
-
-# Deactivate gdump.
-curl -X POST localhost:4000/debug/prof/mem/gdump -d 'activate=false'
-
-# Retrieve current gdump status.
-curl -X GET localhost:4000/debug/prof/mem/gdump
-```
-
-### Dump memory profiling data
-
 Dump memory profiling data through HTTP API:

 ```bash
 curl -X POST localhost:4000/debug/prof/mem > greptime.hprof
-# or output flamegraph directly
-curl -X POST "localhost:4000/debug/prof/mem?output=flamegraph" > greptime.svg
-# or output pprof format
-curl -X POST "localhost:4000/debug/prof/mem?output=proto" > greptime.pprof
 ```

 You can periodically dump profiling data and compare them to find the delta memory usage.

@@ -0,0 +1,72 @@
+Currently, our query engine is based on DataFusion, so all aggregate function is executed by DataFusion, through its UDAF interface. You can find DataFusion's UDAF example [here](https://github.com/apache/arrow-datafusion/blob/arrow2/datafusion-examples/examples/simple_udaf.rs). Basically, we provide the same way as DataFusion to write aggregate functions: both are centered in a struct called "Accumulator" to accumulates states along the way in aggregation.
+
+However, DataFusion's UDAF implementation has a huge restriction, that it requires user to provide a concrete "Accumulator". Take `Median` aggregate function for example, to aggregate a `u32` datatype column, you have to write a `MedianU32`, and use `SELECT MEDIANU32(x)` in SQL. `MedianU32` cannot be used to aggregate a `i32` datatype column. Or, there's another way: you can use a special type that can hold all kinds of data (like our `Value` enum or Arrow's `ScalarValue`), and `match` all the way up to do aggregate calculations. It might work, though rather tedious. (But I think it's DataFusion's prefer way to write UDAF.)
+
+So is there a way we can make an aggregate function that automatically match the input data's type? For example, a `Median` aggregator that can work on both `u32` column and `i32`? The answer is yes until we found a way to bypassing DataFusion's restriction, a restriction that DataFusion simply don't pass the input data's type when creating an Accumulator.

+> There's an example in `my_sum_udaf_example.rs`, take that as quick start.
+
+# 1. Impl `AggregateFunctionCreator` trait for your accumulator creator.
+
+You must first define a struct that will be used to create your accumulator. For example,
+
+```Rust
+#[as_aggr_func_creator]
+#[derive(Debug, AggrFuncTypeStore)]
+struct MySumAccumulatorCreator {}
+```
+
+Attribute macro `#[as_aggr_func_creator]` and derive macro `#[derive(Debug, AggrFuncTypeStore)]` must both annotated on the struct. They work together to provide a storage of aggregate function's input data types, which are needed for creating generic accumulator later.  
+
+> Note that the `as_aggr_func_creator` macro will add fields to the struct, so the struct cannot be defined as an empty struct without field like `struct Foo;`, neither as a new type like `struct Foo(bar)`.
+
+Then impl `AggregateFunctionCreator` trait on it. The definition of the trait is:
+
+```Rust
+pub trait AggregateFunctionCreator: Send + Sync + Debug {
+    fn creator(&self) -> AccumulatorCreatorFunction;
+    fn output_type(&self) -> ConcreteDataType;
+    fn state_types(&self) -> Vec<ConcreteDataType>;
+}
+```
+
+You can use input data's type in methods that return output type and state types (just invoke `input_types()`).
+
+The output type is aggregate function's output data's type. For example, `SUM` aggregate function's output type is `u64` for a `u32` datatype column. The state types are accumulator's internal states' types. Take `AVG` aggregate function on a `i32` column as example, it's state types are `i64` (for sum) and `u64` (for count).
+
+The `creator` function is where you define how an accumulator (that will be used in DataFusion) is created. You define "how" to create the accumulator (instead of "what" to create), using the input data's type as arguments. With input datatype known, you can create accumulator generically.
+
+# 2. Impl `Accumulator` trait for you accumulator.
+
+The accumulator is where you store the aggregate calculation states and evaluate a result. You must impl `Accumulator` trait for it. The trait's definition is:
+
+```Rust
+pub trait Accumulator: Send + Sync + Debug {
+    fn state(&self) -> Result<Vec<Value>>;
+    fn update_batch(&mut self, values: &[VectorRef]) -> Result<()>;
+    fn merge_batch(&mut self, states: &[VectorRef]) -> Result<()>;
+    fn evaluate(&self) -> Result<Value>;
+}
+```
+
+The DataFusion basically execute aggregate like this:
+
+1. Partitioning all input data for aggregate. Create an accumulator for each part.
+2. Call `update_batch` on each accumulator with partitioned data, to let you update your aggregate calculation.
+3. Call `state` to get each accumulator's internal state, the medial calculation result.
+4. Call `merge_batch` to merge all accumulator's internal state to one.
+5. Execute `evaluate` on the chosen one to get the final calculation result.
+
+Once you know the meaning of each method, you can easily write your accumulator. You can refer to `Median` accumulator or `SUM` accumulator defined in  file `my_sum_udaf_example.rs` for more details.
+
+# 3. Register your aggregate function to our query engine.
+
+You can call `register_aggregate_function` method in query engine to register your aggregate function. To do that, you have to new an instance of struct `AggregateFunctionMeta`. The struct has three fields, first is the name of your aggregate function's name. The function name is case-sensitive due to DataFusion's restriction. We strongly recommend using lowercase for your name. If you have to use uppercase name, wrap your aggregate function with quotation marks. For example, if you define an aggregate function named "my_aggr", you can use "`SELECT MY_AGGR(x)`"; if you define "my_AGGR", you have to use "`SELECT "my_AGGR"(x)`".
+
+The second field is arg_counts ,the count of the arguments. Like accumulator `percentile`, calculating the p_number of the column. We need to input the value of column and the value of p to cacalate, and so the count of the arguments is two.
+
+The third field is a function about how to create your accumulator creator that you defined in step 1 above. Create creator, that's a bit intertwined, but it is how we make DataFusion use a newly created aggregate function each time it executes a SQL, preventing the stored input types from affecting each other. The key detail can be starting looking at our `DfContextProviderAdapter` struct's `get_aggregate_meta` method.
+
+# (Optional) 4. Make your aggregate function automatically registered.
+
+If you've written a great aggregate function that want to let everyone use it, you can make it automatically registered to our query engine at start time. It's quick simple, just refer to the `AggregateFunctions::register` function in `common/function/src/scalars/aggregate/mod.rs`.

 ## What is a fuzz test
-Fuzz test is tool that leverages deterministic random generation to assist in finding bugs. The goal of fuzz tests is to identify inputs generated by the fuzzer that cause system panics, crashes, or unexpected behaviors to occur. And we are using the [cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz) to run our fuzz test targets.

 Figure 1 illustrates the fundamental components of the fuzz test provide the ability to generate random SQLs. It utilizes a Random Number Generator (Rng) to generate the Intermediate Representation (IR), then employs a DialectTranslator to produce specified dialects for different protocols. Finally, the fuzz tests send the generated SQL via the specified protocol and verify that the execution results meet expectations.

-# Memory Analysis Process
-This section will guide you through the process of analyzing memory usage for greptimedb.
-
-1. Get the `jeprof` tool script, see the next section("Getting the `jeprof` tool") for details.
-
-2. After starting `greptimedb`(with env var `MALLOC_CONF=prof:true`), execute the `dump.sh` script with the PID of the `greptimedb` process as an argument. This continuously monitors memory usage and captures profiles when exceeding thresholds (e.g. +20MB within 10 minutes). Outputs `greptime-{timestamp}.gprof` files.
-
-3. With 2-3 gprof files, run `gen_flamegraph.sh` in the same environment to generate flame graphs showing memory allocation call stacks.
-
-4.  **NOTE:** The `gen_flamegraph.sh` script requires `jeprof` and optionally `flamegraph.pl` to be in the current directory. If needed to gen flamegraph now, run the `get_flamegraph_tool.sh` script, which downloads the flame graph generation tool `flamegraph.pl` to the current directory.
-    The usage of `gen_flamegraph.sh` is:
-
-    `Usage: ./gen_flamegraph.sh <binary_path> <gprof_directory>`
-    where `<binary_path>` is the path to the greptimedb binary, `<gprof_directory>` is the directory containing the gprof files(the directory `dump.sh` is dumping profiles to).
-    Example call: `./gen_flamegraph.sh ./greptime .`
-
-    Generating the flame graph might take a few minutes. The generated flame graphs are located in the `<gprof_directory>/flamegraphs` directory. Or if no `flamegraph.pl` is found, it will only contain `.collapse` files which is also fine.
-5.  You can send the generated flame graphs(the entire folder of `<gprof_directory>/flamegraphs`) to developers for further analysis.
-
-
-## Getting the `jeprof` tool
-there are three ways to get `jeprof`, list in here from simple to complex, using any one of those methods is ok, as long as it's the same environment as the `greptimedb` will be running on:
-1. If you are compiling greptimedb from source, then `jeprof` is already produced during compilation. After running `cargo build`, execute `find_compiled_jeprof.sh`. This will copy `jeprof` to the current directory.
-2. Or, if you have the Rust toolchain installed locally, simply follow these commands:
-```bash
-cargo new get_jeprof
-cd get_jeprof
-```
-Then add this line to `Cargo.toml`:
-```toml
-[dependencies]
-tikv-jemalloc-ctl = { version = "0.6", features = ["use_std", "stats"] }
-```
-then run:
-```bash
-cargo build
-```
-after that the `jeprof` tool is produced. Now run `find_compiled_jeprof.sh` in current directory, it will copy the `jeprof` tool to the current directory.
-
-3. compile jemalloc from source
-you can first clone this repo, and checkout to this commit:
-```bash
-git clone https://github.com/tikv/jemalloc.git
-cd jemalloc
-git checkout e13ca993e8ccb9ba9847cc330696e02839f328f7
-```
-then run:
-```bash
-./configure
-make
-```
-and `jeprof` is in `.bin/` directory. Copy it to the current directory.

Firstly, it boasts ease of comprehension and customization. Secondly, the dataflow framework offers precisely the necessary features for crafting uncomplicated single-node dataflow programs while delivering decent performance.

 Hence, we choose the third option, and use a simple logical plan that's anagonistic to the underlying dataflow framework, as it only describe how the dataflow graph should be doing, not how it do that. And we built operator in hydroflow to execute the plan. And the result hydroflow graph is wrapped in a engine that only support data in/out and tick event to flush and compute the result. This provide a thin middle layer that's easy to maintain and allow switching to other dataflow framework if necessary.

-Feature Name: Remote WAL Purge

-
-# Summary
-
-This RFC proposes a method for purging remote WAL in the database.
-
-# Motivation
-
-Currently only local wal entries are purged when flushing, while remote wal does nothing.
-
-# Details
-
-```mermaid
-sequenceDiagram
-    Region0->>Kafka: Last entry id of the topic in use
-    Region0->>WALPruner: Heartbeat with last entry id
-    WALPruner->>+WALPruner: Time Loop
-    WALPruner->>+ProcedureManager: Submit purge procedure
-    ProcedureManager->>Region0: Flush request
-    ProcedureManager->>Kafka: Prune WAL entries
-    Region0->>Region0: Flush
-```
-
-## Steps
-
-### Before purge
-
-Before purging remote WAL, metasrv needs to know:
-
-1. `last_entry_id` of each region.
-2. `kafka_topic_last_entry_id` which is the last entry id of the topic in use. Can be lazily updated and needed when region has empty memtable.
-3. Kafka topics that each region uses.
-
-The states are maintained through:
-1. Heartbeat: Datanode sends `last_entry_id` to metasrv in heartbeat. As for regions with empty memtable, `last_entry_id` should equals to `kafka_topic_last_entry_id`.
-2. Metasrv maintains a topic-region map to know which region uses which topic.
-
-`kafka_topic_last_entry_id` will be maintained by the region itself. Region will update the value after `k` heartbeats if the memtable is empty.
-
-### Purge procedure
-
-We can better handle locks utilizing current procedure. It's quite similar to the region migration procedure.
-
-After a period of time, metasrv will submit a purge procedure to ProcedureManager. The purge will apply to all topics.
-
-The procedure is divided into following stages:
-
-1. Preparation:
-   - Retrieve `last_entry_id` of each region kvbackend.
-   - Choose regions that have a relatively small `last_entry_id` as candidate regions, which means we need to send a flush request to these regions.
-2. Communication:
-   - Send flush requests to candidate regions.
-3. Purge:
-   - Choose proper entry id to delete for each topic. The entry should be the smallest `last_entry_id - 1` among all regions. 
-   - Delete legacy entries in Kafka.
-   - Store the `last_purged_entry_id` in kvbackend. It should be locked to prevent other regions from replaying the purged entries.
-
-### After purge
-
-After purge, there may be some regions that have `last_entry_id` smaller than the entry we just deleted. It's legal since we only delete the entries that are not needed anymore.
-
-When restarting a region, it should query the `last_purged_entry_id` from metasrv and replay from `min(last_entry_id, last_purged_entry_id)`.
-
-### Error handling
-
-No persisted states are needed since all states are maintained in kvbackend.
-
-Retry when failed to retrieving metadata from kvbackend.
-
-# Alternatives
-
-Purge time can depend on the size of the WAL entries instead of a fixed period of time, which may be more efficient.

-# Summary
-
-This RFC proposes a method for repartitioning a table, to adjust the partition rule and data distribution.
-
-# Motivation
-
-With time passing, the data distribution and skew pattern of a table might change. We need a way to repartition the table to suit the new pattern.
-
-# Details
-
-Here is a rough workflow diagram of the entire repartition process, each step is described in detail below.

-```
-
-## Preprocessing
-
-This phase is for static analysis of the new partition rule. The server can know whether the repartitioning is possible, how to do the repartitioning, and how much resources are needed.
-
-In theory, the input and output partition rules for repartitioning can be completely unrelated. But in practice, to avoid a very large change set, we'll only allow two simple kinds of change. One splits one region into two regions (region split) and another merges two regions into one (region merge).
-
-After validating the new partition rule using the same validation logic as table creation, we compute the difference between the old and new partition rules. The resulting diff may contain several independent groups of changes. During subsequent processing, each group of changes can be handled independently and can succeed or fail without affecting other groups or creating non-idempotently retryable scenarios.
-
-Next, we generate a repartition plan for each group of changes. Each plan contains this information for all regions involved in that particular plan. And one target region will only be referenced by a single plan.
-
-With those plans, we can determine the resource requirements for the repartition operation, where resources here primarily refer to Regions. Metasrv will coordinate with PaaS layer to pre-allocate the necessary regions at this stage. These new regions start completely empty, and their metadata and manifests will be populated during subsequent modification steps.
-
-## Data Processing
-
-This phase is primarily for region's change, including region's metadata (route table and the corresponding rule) and manifest.
-
-Once we start processing one plan through a procedure, we'll first stop the region's compaction and snapshot. This is to avoid any states being removed due to compaction (which may removes old SST files) and snapshot (which may removes old manifest files).
-
-Metasrv will trying to update the metadata of partition, or the region route table (related to `PartitionRuleManager`). This step is in the "no ingestion" scope, so no new data will be ingested. Since this won't take much time, the affection to the cluster is minimized. Metasrv will also update the region rule to corresponding regions on Datanodes. 
-
-Every regions and all the ingestion requests to the region server will have a version of region rule, to identify under which rule the request is processed. The version can be something like `hash(region_rule)`. Once the region rule on region server is updated, all ingestion request with old rule will be rejected, and all requests with new rule will be accepted but not visible. They can still be flushed to persisted storage, but their version change (new manifest) will be staged.
-
-Then region 0 (or let metasrv to pick any operational region) will compute the new manifests for all target regions. This step is done by first reading all old manifests, and remapping the files with new partition rule, to get the content of new manifests. Notice this step only handles the manifests before region rule change on region server, and won't touch those staged manifests, as they are already with the new rule.
-
-Those new manifest will be submitted to the corresponding target regions by region 0 via a `RegionEdit` request. If this request falls after a few retries, region 0 will try to rollback this change by directly overwriting the manifest on object storage. and report this failure to metasrv and let the entire repartition procedure to fail. And we can also optionally compute the new manifest for those staged version changes (like another repartition) and submit them to the target regions to make the also visible even if the repartition fails.
-
-In the other hand, a successful `RegionEdit` request also acknowledges those staged version changes and make them visible.
-
-After this step, the repartition is done in the data plane. We can start to process compaction and snapshot again.
-
-## Postprocessing
-
-After the main processing is done, we can do some extra postprocessing to reduce the performance impact of repartition. Including reloading caches in frontend's route table, metasrv's kv cache and datanode's read/write/page cache etc.
-
-We can also schedule an optional compaction to reorganize all the data file under the new partition rule to reduce potential fragmentation or read amplification.
-
-## Procedure
-
-Here describe the repartition procedure step by step:
-
- <on frontend> Validating repartition request
- <on frontend> Initialize the repartition procedure
- Calculate rule diff and repartition plan group
- Allocate necessary new regions
- Lock the table key
- For each repartition subprocedure
-  - Stop compaction and snapshot
-  - Forbid new ingestion requests, update metadata, allow ingestion requests.
-  - Update region rule to regions
-  - Pick one region to calculate new manifest for all regions in this repartition group
-  - Let that region to apply new manifest to each region via `RegionEdit`
-  - If failed after some retries, revert this manifest change to other succeeded regions and mark this failure.
-  - If all succeeded, acknowledge those staged version changes and make them visible.
-  - Return result
- Collect results from subprocedure.
-  - For those who failed, we need to restart those regions to force reconstruct their status from manifests
-  - For those who succeeded, collect and merge their rule diff
- Unlock the table key
- Report the result to user.
- <in background> Reload cache
- <in background> Maybe trigger a special compaction
-
-In addition of sequential step, rollback is also an important part of this procedure. There are three steps can be rolled back when unrecoverable failure occurs.
-
-If the metadata update is not committed, we can overwrite the metadata to previous version. This step is scoped in the "no ingestion" period, so no new data will be ingested and the status of both datanode and metasrv will be consistent.
-
-If the `RegionEdit` to other regions is not acknowledged, or partial acknowledged, we can directly overwrite the manifest on object storage from the central region (who computes the new manifest), and force region server to reload corresponding region to load its state from object storage to recover.
-
-If the staged version changes are not acknowledged, we can re-compute manifest based on old rule for staged data, and apply them directly like above. This is like another smaller repartition for those staged data.
-
-## Region rule validation and diff calculation
-
-In the current codebase, the rule checker is not complete. It can't check uniqueness and completeness of the rule. This RFC also propose a new way to validate the rule.
-
-The proposed validation way is based on a check-point system, which first generates a group of check-points from the rule, and then check if all the point is covered and only covered by one rule.
-
-All the partition rule expressionis limited to be the form of `<column> <operator> <value>`, and the operator is limited to be comparison operators. Those expressions are allowed to be nested with `AND` and `OR` operators. Based on this, we can first extract all the unique values on each column, adding and subtracting a little epsilon to cover its left and right boundary.
-
-Since we accept integer, float and string as the value type, compute on them directly is not convenient. So we'll first normalize them to a common type and only need to preserve the relative partial ordering. This also avoids the problem of "what is next/previous value" of string and "what's a good precision" for float.
-
-After normalization, we get a set of scatter points for each column. Then we can generate a set of check-points by combining all the scatter points like building a cartesian product. This might bring a large number of check-points, so we can do an prune optimization to remove some of them by merging some of the expression zones. Those expressions who have identical N-1 edge sub-expressions with one adjacent edge can be merged together. This prune check is with a time complexity of O(N * M * log(M)), where N is the number of active dimensions and M is the number of expression zones. Diff calculation is also done by finding different expression zones between the old and new rule set, and check if we can transform one to another by merging some of the expression zones.
-
-The step to validate the check-points set against expressions can be treated as a tiny expression of `PhysicalExpr`. This evaluation will give a boolean matrix of K*M shape, where K is the number of check-points. We then check in each row of the matrix, if there is one and only one true value.
-
-## Compute and use new manifest
-
-We can generate a new set of manifest file based on old manifest and two versions of rule. From abvoe rule processing part, we can tell how a new rule & region is from previous one. So a simple way to get the new manifest is also apply the step of change to manifest files. E.g., if region A is from region B and C, we simply combine all file IDs from B and C to generate the content of A.
-
-If necessary, we can do this better by involving some metadata related to data, like min-max statistics of each file, and pre-evaluate over min-max to filter out unneeded files when generating new manifest.
-
-The way to use new manifest needs one more extra step based on the current implementation. We'll need to record either in manifest or in file metadata, of what rule is used when generating (flush or compaction) a SST file. Then in every single read request, we need to append the current region rule as predicate to the read request, to ensure no data belong to other regions will be read. We can use the stored region rule to reduce the number of new predicates to apply, by removing the identical predicate between the current region rule and the stored region rule. So ideally in a table that has not been repartitioned recently, the overhead of checking region rule is minimal.
-
-## Pre-required tasks
-
-In above steps, we assume some functionalities are implemented. Here list them with where they are used and how to implement them.
-
-### Cross-region read
-
-The current data directory structure is `{table_id}/{region_id}/[data/metadata]/{file_id}`, every region can only access files under their own directory. After repartition, data file may be placed in other previous old regions. So we need to support cross-region read. This new access method allows region to access any file under the same table. Related tracking issue is <https://github.com/GreptimeTeam/greptimedb/issues/6409>.
-
-### Global GC worker
-
-This is to simplify state management of data files. As one file may be referenced in multiple manifests, or no manifest at all. After this, every region and the repartition process only need to care about generateing and using new files, without tracking whether a file should be deleted or not. Leaving the deletion to the global GC worker. This worker basically works by counting reference from manifest file, and remove unused one. Related tracking issue is **TBD**.
-
-# Alternatives
-
-In the "Data Processing" section, we can enlarge the "no ingestion" period to include almost all the steps. This can simplify the entire procedure by a lot, but will bring a longer time of ingestion pause which may not be acceptable.

-Feature Name: Compatibility Test Framework
-Tracking Issue: TBD
-Date: 2025-07-04
-Author: "Ruihang Xia <waynestxia@gmail.com>"
---
-
-# Summary
-
-This RFC proposes a compatibility test framework for GreptimeDB to ensure backward/forward compatibility for different versions of GreptimeDB.
-
-# Motivation
-
-In current practice, we don't have a systematic way to test and ensure the compatibility of different versions of GreptimeDB. Each time we release a new version, we need to manually test the compatibility with ad-hoc cases. This is not only time-consuming, but also prone to errors and unmaintainable. Highly rely on the release manager to ensure the compatibility of different versions of GreptimeDB.
-
-We don't have a detailed guide on the release SoP of how to test and ensure the compatibility of the new version. And has broken the compatibility of the new version many times (`v0.14.1` and `v0.15.1` are two examples, which are both released right after the major release).
-
-# Details
-
-This RFC proposes a compatibility test framework that is easy to maintain, extend and run. It can tell the compatibility between any given two versions of GreptimeDB, both backward and forward. It's based on the Sqlness library but used in a different way.
-
-Generally speaking, the framework is composed of two parts:
-
-1. Test cases: A set of test cases that are maintained dedicatedly for the compatibility test. Still in the `.sql` and `.result` format.
-2. Test framework: A new sqlness runner that is used to run the test cases. With some new features that is not required by the integration sqlness test.
-
-## Test Cases
-
-### Structure
-
-The case set is organized in three parts:
-
- `1.feature`: Use a new feature
- `2.verify`: Verify database behavior
- `3.cleanup`: Paired with `1.feature`, cleanup the test environment.
-
-These three parts are organized in a tree structure, and should be run in sequence:
-
-```
-compatibility_test/
-├── 1.feature/
-│   ├── feature-a/
-│   ├── feature-b/
-│   └── feature-c/
-├── 2.verify/
-│   ├── verify-metadata/
-│   ├── verify-data/
-│   └── verify-schema/
-└── 3.cleanup/
-    ├── cleanup-a/
-    ├── cleanup-b/
-    └── cleanup-c/
-```
-
-### Example
-
-For example, for a new feature like adding new index option ([#6416](https://github.com/GreptimeTeam/greptimedb/pull/6416)), we (who implement the feature) create a new test case like this:
-
-```sql
-- path: compatibility_test/1.feature/index-option/granularity_and_false_positive_rate.sql
-
-- SQLNESS ARG since=0.15.0
-- SQLNESS IGNORE_RESULT
-CREATE TABLE granularity_and_false_positive_rate (ts timestamp time index, val double) with ("index.granularity" = "8192", "index.false_positive_rate" = "0.01");
-```
-
-And
-
-```sql
-- path: compatibility_test/3.cleanup/index-option/granularity_and_false_positive_rate.sql
-drop table granularity_and_false_positive_rate;
-```
-
-Since this new feature don't require some special way to verify the database behavior, we can reuse existing test cases in `2.verify/` to verify the database behavior. For example, we can reuse the `verify-metadata` test case to verify the metadata of the table.
-
-```sql
-- path: compatibility_test/2.verify/verify-metadata/show-create-table.sql
-
-- SQLNESS TEMPLATE TABLE="SHOW TABLES";
-SHOW CREATE TABLE $TABLE;
-```
-
-In this example, we use some new sqlness features that will be introduced in the next section (`since`, `IGNORE_RESULT`, `TEMPLATE`).
-
-### Maintenance
-
-Each time implement a new feature that should be covered by the compatibility test, we should create a new test case in `1.feature/` and `3.cleanup/` for them. And check if existing cases in `2.verify/` can be reused to verify the database behavior.
-
-This simulates an enthusiastic user who uses all the new features at the first time. All the new Maintenance burden is on the feature implementer to write one more test case for the new feature, to "fixation" the behavior. And once there is a breaking change in the future, it can be detected by the compatibility test framework automatically.
-
-Another topic is about deprecation. If a feature is deprecated, we should also mark it in the test case. Still use above example, assume we deprecate the `index.granularity` and `index.false_positive_rate` index options in `v0.99.0`, we can mark them as:
-```sql
-- SQLNESS ARG since=0.15.0 till=0.99.0
-...
-```
-
-This tells the framework to ignore this feature in version `v0.99.0` and later. Currently, we have so many experimental features that are scheduled to be broken in the future, this is a good way to mark them.
-
-## Test Framework
-
-This section is about new sqlness features required by this framework.
-
-### Since and Till
-
-Follows the `ARG` interceptor in sqlness, we can mark a feature is available between two given versions. Only the `since` is required:
-
-```sql
-- SQLNESS ARG since=VERSION_STRING [till=VERSION_STRING]
-```
-
-### IGNORE_RESULT
-
-`IGNORE_RESULT` is a new interceptor, it tells the runner to ignore the result of the query, only check whether the query is executed successfully.
-
-This is useful to reduce the Maintenance burden of the test cases, unlike the integration sqlness test, in most cases we don't care about the result of the query, only need to make sure the query is executed successfully.
-
-### TEMPLATE
-
-`TEMPLATE` is another new interceptor, it can generate queries from a template based on a runtime data.
-
-In above example, we need to run the `SHOW CREATE TABLE` query for all existing tables, so we can use the `TEMPLATE` interceptor to generate the query with a dynamic table list.
-
-### RUNNER
-
-There are also some extra requirement for the runner itself:
-
- It should run the test cases in sequence, first `1.feature/`, then `2.verify/`, and finally `3.cleanup/`.
- It should be able to fetch required version automatically to finish the test.
- It should handle the `since` and `till` properly.
-
-On the `1.feature` phase, the runner needs to identify all features need to be tested by version number. And then restart with a new version (the `to` version) to run `2.verify/` and `3.cleanup/` phase.
-
-## Test Report
-
-Finally, we can run the compatibility test to verify the compatibility between any given two versions of GreptimeDB, for example:
-
-```bash
-# check backward compatibility between v0.15.0 and v0.16.0 when releasing v0.16.0
-./sqlness run --from=0.15.0 --to=0.16.0
-
-# check forward compatibility when downgrading from v0.15.0 to v0.13.0
-./sqlness run --from=0.15.0 --to=0.13.0
-```
-
-We can also use a script to run the compatibility test for all the versions in a given range to give a quick report with all versions we need.
-
-And we always bump the version in `Cargo.toml` to the next major release version, so the next major release version can be used as "latest" unpublished version for scenarios like local testing.
-
-# Alternatives
-
-There was a previous attempt to implement a compatibility test framework that was disabled due to some reasons [#3728](https://github.com/GreptimeTeam/greptimedb/issues/3728).

-# Global GC Worker
-
-## Summary
-
-This RFC proposes the integration of a garbage collection (GC) mechanism within the Compaction process. This mechanism aims to manage and remove stale files that are no longer actively used by any system component, thereby reclaiming storage space.
-
-## Motivation
-
-With the introduction of features such as table repartitioning, a substantial number of Parquet files can become obsolete. Furthermore, failures during manifest updates may result in orphaned files that are never referenced by the system. Therefore, a periodic garbage collection mechanism is essential to reclaim storage space by systematically removing these unused files.
-
-## Details
-
-### Overview
-
-The garbage collection process will be integrated directly into the Compaction process. Upon the completion of a Compaction for a given region, the GC worker will be automatically triggered. Its primary function will be to identify and subsequently delete obsolete files that have persisted beyond their designated retention period. This integration ensures that garbage collection is performed in close conjunction with data lifecycle management, effectively leveraging the compaction process's inherent knowledge of file states.
-
-This design prioritizes correctness and safety by explicitly linking GC execution to a well-defined operational boundary: the successful completion of a compaction cycle.
-
-### Terminology
-
- **Unused File**: Refers to a file present in the storage directory that has never been formally recorded in any manifest. A common scenario for this includes cases where a new SST file is successfully written to storage, but the subsequent update to the manifest fails, leaving the file unreferenced.
- **Obsolete File**: Denotes a file that was previously recorded in a manifest but has since been explicitly marked for removal. This typically occurs following operations such as data repartitioning or compaction.
-
-### GC Worker Process
-
-The GC worker operates as an integral part of the Compaction process. Once a Compaction for a specific region is completed, the GC worker is automatically triggered. Executing this process on a `datanode` is preferred to eliminate the overhead associated with having to set object storage configurations in the `metasrv`.
-
-The detailed process is as follows:
-
-1.  **Invocation**: Upon the successful completion of a Compaction for a region, the GC worker is invoked.
-2.  **Manifest Reading**: The worker reads the region's primary manifest to obtain a comprehensive list of all files marked as obsolete. Concurrently, it reads any temporary manifests generated by long-running queries to identify files that are currently in active use, thereby preventing their premature deletion.
-3.  **Lingering Time Check (Obsolete Files)**: For each identified obsolete file, the GC worker evaluates its "lingering time." Which is the time passed after it had been removed from manifest.
-4.  **Deletion Marking (Obsolete Files)**: Files that have exceeded their maximum configurable lingering time and are not referenced by any active temporary manifests are marked for deletion.
-5.  **Lingering Time (Unused Files)**: Unused files (those never recorded in any manifest) are also subject to a configurable maximum lingering time before they are eligible for deletion.
-
-Following flowchart illustrates the GC worker's process:

-```
-
-#### Handling Obsolete Files
-
-An obsolete file is permanently deleted only if two conditions are met:
-1. The time elapsed since its removal from the manifest (its obsolescence timestamp) exceeds a configurable threshold.
-2. It is not currently referenced by any active temporary manifests.
-
-
-#### Handling Unused Files
-
-With the integration of the GC worker into the Compaction process, the risk of accidentally deleting newly created SST files that have not yet been recorded in the manifest is significantly mitigated. Consequently, the concept of "Unused Files" as a distinct category primarily susceptible to accidental deletion is largely resolved. Any files that are genuinely "unused" (i.e., never referenced by any manifest, including temporary ones) can be safely deleted after a configurable maximum lingering time.
-
-For debugging and auditing purposes, a comprehensive list of recently deleted files can be maintained.
-
-### Ensuring Read Consistency
-
-To prevent the GC worker from inadvertently deleting files that are actively being utilized by long-running analytical queries, a robust protection mechanism is introduced. This mechanism relies on temporary manifests that are actively kept "alive" by the queries using them.
-
-When a long-running query is detected (e.g., by a slow query recorder), it will write a temporary manifest to the region's manifest directory. This manifest lists all files required for the query. However, simply creating this file is not enough, as a query runner might crash, leaving the temporary manifest orphaned and preventing garbage collection indefinitely.
-
-To address this, the following "heartbeat" mechanism is implemented:
-1.  **Periodic Updates**: The process executing the long-running query is responsible for periodically updating the modification timestamp of its temporary manifest file (i.e., "touching" the file). This serves as a heartbeat, signaling that the query is still active.
-2.  **GC Worker Verification**: When the GC worker runs, it scans for temporary manifests. For each one it finds, it checks the file's last modification time.
-3.  **Stale File Handling**: If a temporary manifest's last modification time is older than a configurable threshold, the GC worker considers it stale (left over from a crashed or terminated query). The GC worker will then delete this stale temporary manifest. Files that were protected only by this stale manifest are no longer shielded from garbage collection.
-
-This approach ensures that only files for genuinely active queries are protected. The lifecycle of the temporary manifest is managed dynamically: it is created when a long query starts, kept alive through periodic updates, and is either deleted by the query upon normal completion or automatically cleaned up by the GC worker if the query terminates unexpectedly.
-
-This mechanism may be too complex to implement at once. We can consider a two-phased approach:
-1.  **Phase 1 (Simple Time-Based Deletion)**: Initially, implement a simpler GC strategy that deletes obsolete files based solely on a configurable lingering time. This provides a baseline for space reclamation without the complexity of temporary manifests.
-2.  **Phase 2 (Consistency-Aware GC)**: Based on the practical effectiveness and observed issues from Phase 1, we can then decide whether to implement the full temporary manifest and heartbeat mechanism to handle long-running queries. This iterative approach allows for a quicker initial implementation while gathering real-world data to justify the need for a more complex solution.
-
-## Drawbacks
-
- **Dependency on Compaction Frequency**: The integration of the GC worker with Compaction means that GC cycles are directly tied to the frequency of compactions. In environments with infrequent compaction operations, obsolete files may accumulate for extended periods before being reclaimed, potentially leading to increased storage consumption.
- **Race Condition with Long-Running Queries**: A potential race condition exists if a long-running query initiates but haven't write its temporary manifest in time, while a compaction process simultaneously begins and marks files used by that query as obsolete. This scenario could lead to the premature deletion of files still required by the active query. To mitigate this, the threshold time for writing a temporary manifest should be significantly shorter than the lingering time configured for obsolete files, ensuring that next GC worker runs do not delete files that are now referenced by a temporary manifest if the query is still running.
-Also the read replica shouldn't be later in manifest version for more than the lingering time of obsolete files, otherwise it might ref to files that are already deleted by the GC worker.
- need to upload tmp manifest to object storage, which may introduce additional complexity and potential performance overhead. But since long-running queries are typically not frequent, the performance impact is expected to be minimal.
-
-one potential race condition with region-migration is illustrated below:
-
-```mermaid
-sequenceDiagram
-    participant gc_worker as GC Worker(same dn as region 1)
-    participant region1 as Region 1 (Leader → Follower)
-    participant region2 as Region 2 (Follower → Leader)
-    participant region_dir as Region Directory
-
-    gc_worker->>region1: Start GC, get region manifest
-    activate region1
-    region1-->>gc_worker: Region 1 manifest
-    deactivate region1
-    gc_worker->>region_dir: Scan region directory
-
-    Note over region1,region2: Region Migration Occurs
-    region1-->>region2: Downgrade to Follower
-    region2-->>region1: Becomes Leader
-
-    region2->>region_dir: Add new file
-
-    gc_worker->>region_dir: Continue scanning
-    gc_worker-->>region_dir: Discovers new file
-    Note over gc_worker: New file not in Region 1's manifest
-    gc_worker->>gc_worker: Mark file as orphan(incorrectly)
-```
-which could cause gc worker to incorrectly mark the new file as orphan and delete it, if config the lingering time for orphan files(files not mentioned anywhere(in used or unused)) is not long enough.
-
-A good enough solution could be to use lock to prevent gc worker to happen on the region if region migration is happening on the region, and vise versa.
-
-The race condition between gc worker and repartition also needs to be considered carefully. For now, acquiring lock for both region-migration and repartition during gc worker process could be a simple solution.
-
-## Conclusion and Rationale
-
-This section summarizes the key aspects and trade-offs of the proposed integrated GC worker, highlighting its advantages and potential challenges.
-
-| Aspect | Current Proposal (Integrated GC) |
-| :--- | :--- |
-| **Implementation Complexity** | **Medium**. Requires careful integration with the compaction process and the slow query recorder for temporary manifest management. |
-| **Reliability** | **High**. Integration with compaction and leveraging temporary manifests from long-running queries significantly mitigates the risk of incorrect deletion. Accurate management of lingering times for obsolete files and prevention of accidental deletion of newly created SSTs enhance data safety. |
-| **Performance Overhead** | **Low to Medium**. The GC worker runs post-compaction, minimizing direct impact on write paths. Overhead from temporary manifest management by the slow query recorder is expected to be acceptable for long-running queries. |
-| **Impact on Other Components** | **Moderate**. Requires modifications to the compaction process to trigger GC and the slow query recorder to manage temporary manifests. This introduces some coupling but enhances overall data safety. |
-| **Deletion Strategy** | **State- and Time-Based**. Obsolete files are deleted based on a configurable lingering time, which is paused if the file is referenced by a temporary manifest. Unused files (never in a manifest) are also subject to a lingering time. |
-
-## Unresolved Questions and Future Work
-
-This section outlines key areas requiring further discussion and defines potential avenues for future development.
-
-*   **Slow Query Recorder Implementation**: Detailed specifications for modify slow query recorder's implementation and its precise interaction mechanisms with temporary manifests are needed.
-*   **Configurable Lingering Times**: Establish and make configurable the specific lingering times for both obsolete and unused files to optimize storage reclamation and data availability.
-
-## Alternatives
-
-### 1. Standalone GC Service
-
-Instead of integrating the GC worker directly into the Compaction process, a standalone GC service could be implemented. This service would operate independently, periodically scanning the storage for obsolete and unused files based on manifest information and predefined retention policies.
-
-**Pros:**
-*   **Decoupling**: Separates GC logic from compaction, allowing independent scaling and deployment.
-*   **Flexibility**: Can be configured to run at different frequencies and with different strategies than compaction.
-
-**Cons:**
-*   **Increased Complexity**: Requires a separate service to manage, monitor, and coordinate with other components.
-*   **Potential for Redundancy**: May duplicate some file scanning logic already present in compaction.
-*   **Consistency Challenges**: Ensuring read consistency would require more complex coordination mechanisms between the standalone GC service and active queries, potentially involving a distributed lock manager or a more sophisticated temporary manifest system.
-
-This alternative could be implemented in the future if the integrated GC worker proves insufficient or if there is a need for more advanced GC strategies.
-
-### 2. Manifest-Driven Deletion (No Lingering Time)
-
-This alternative would involve immediate deletion of files once they are removed from the manifest, without a lingering time.
-
-**Pros:**
-*   **Simplicity**: Simplifies the GC logic by removing the need for lingering time management.
-*   **Immediate Space Reclamation**: Storage space is reclaimed as soon as files are marked for deletion.
-
-**Cons:**
-*   **Increased Risk of Data Loss**: Higher risk of deleting files still in use by long-running queries or other processes if not perfectly synchronized.
-*   **Complex Read Consistency**: Requires extremely robust and immediate mechanisms to ensure that no active queries are referencing files marked for deletion, potentially leading to performance bottlenecks or complex error handling.
-*   **Debugging Challenges**: Difficult to debug issues related to premature file deletion due to the immediate nature of the operation.

-Feature Name: Async Index Build

-# Summary
-This RFC proposes an asynchronous index build mechanism in the database, with a configuration option to choose between synchronous and asynchronous modes, aiming to improve flexibility and adapt to different workload requirements.
-
-# Motivation
-Currently, index creation is performed synchronously, which may lead to prolonged write suspension and impact business continuity. As data volume grows, the time required for index building increases significantly. An asynchronous solution is urgently needed to enhance user experience and system throughput.
-
-# Details
-
-## Overview
-
-The following table highlights the difference between async and sync index approach:
-
-| Approach | Trigger | Data Source | Additional Index Metadata Installation | Fine-grained `FileMeta` Index |
-| :--- | :--- | :--- | :--- | :--- |
-| Sync Index | On `write_sst` | Memory (on flush) / Disk (on compact) | Not required(already installed synchronously) | Not required |
-| Async Index | 4 trigger types | Disk | Required | Required |
-
-The index build mode (synchronous or asynchronous) can be selected via configuration file. 
-
-### Four Trigger Types
-
-This RFC introduces four `IndexBuildType`s to trigger index building:
-
- **Manual Rebuild**: Triggered by the user via `ADMIN build_index("table_name")`, for scenarios like recovering from failed builds or migrating data. SST files whose `ColumnIndexMetadata` (see below) is already consistent with the `RegionMetadata` will be skipped.
- **Schema Change**: Automatically triggered when the schema of an indexed column is altered.
- **Flush**: Automatically builds indexes for new SST files created by a flush.
- **Compact**: Automatically builds indexes for new SST files created by a compaction.
-
-### Additional Index Metadata Installation
-
-Previously, index information in the in-memory `FileMeta` was updated synchronously. The async approach requires an explicit installation step.
-
-A race condition can occur when compaction and index building run concurrently, leading to:
-1. Building an index for a file that is about to be deleted by compaction.
-2. Creating an unnecessary index file and an incorrect manifest record.
-3. On restart, replaying the manifest could load metadata for a non-existent file.
-
-To prevent this, the system checks if a file's `FileMeta` is in a `compacting` state before updating the manifest. If it is, the installation is aborted.
-
-### Fine-grained `FileMeta` Index
-
-The original `FileMeta` only stored file-level index information. However, manual rebuilds require column-level details to identify files inconsistent with the current DDL. Therefore, the `indexes` field in `FileMeta` is updated as follows:
-```rust
-struct FileMeta {
-    ...
-    // From file-level:
-    // available_indexes: SmallVec<[IndexType; 4]>
-    // To column-level:
-    indexes: Vec<ColumnIndexMetadata>,
-    ...
-}
-pub struct ColumnIndexMetadata {
-    pub column_id: ColumnId,
-    pub created_indexes: IndexTypes,
-}
-```
-
-## Process
-
-The index building process is similar to a flush and is illustrated below:
-
-```mermaid
-sequenceDiagram
-    Region0->>Region0: Triggered by one of 4 conditions, targets specific files
-    loop For each target file
-    Region0->>IndexBuildScheduler: Submits an index build task
-    end
-    IndexBuildScheduler->>IndexBuildTask: Executes the task
-    IndexBuildTask->>Storage Interfaces: Reads SST data from disk
-    IndexBuildTask->>IndexBuildTask: Builds the index file
-    alt Index file size > 0
-    IndexBuildTask->>Region0: Sends IndexBuildFinished notification
-    end
-    alt File exists in Version and is not compacting
-    Region0->>Storage Interfaces: Updates manifest and Version
-    end
-```
-
-### Task Triggering and Scheduling
-
-The process starts with one of the four `IndexBuildType` triggers. In `handle_rebuild_index`, the `RegionWorkerLoop` identifies target SSTs from the request or the current region version. It then creates an `IndexBuildTask` for each file and submits it to the `index_build_scheduler`.
-
-Similar to Flush and Compact operations, index build tasks are ultimately dispatched to the LocalScheduler. Resource usage can be adjusted via configuration files. Since asynchronous index tasks are both memory-intensive and IO-intensive but have lower priority, it is recommended to allocate fewer resources to them compared to compaction and flush tasks—for example, limiting them to 1/8 of the CPU cores. 
-
-### Index Building and Notification
-
-The scheduled `IndexBuildTask` executes its `index_build` method. It uses an `indexer_builder` to create an `Indexer` that reads SST data and builds the index. If a new index file is created (`IndexOutput.file_size > 0`), the task sends an `IndexBuildFinished` notification back to the `RegionWorkerLoop`.
-
-### Index Metadata Installation
-
-Upon receiving the `IndexBuildFinished` notification in `handle_index_build_finished`, the `RegionWorkerLoop` verifies that the file still exists in the current `version` and is not being compacted. If the check passes, it calls `manifest_ctx.update_manifest` to apply a `RegionEdit` with the new index information, completing the installation.
-
-# Drawbacks
-
-Asynchronous index building may consume extra system resources, potentially affecting overall performance during peak periods.
-
-There may be a delay before the new index becomes available for queries, which could impact certain use cases.
-
-# Unresolved Questions and Future Work
-
-**Resource Management and Throttling**: The resource consumption (CPU, I/O) of background index building can be managed and limited to some extent by configuring a dedicated background thread pool. However, this approach cannot fully eliminate resource contention, especially under heavy workloads or when I/O is highly competitive. Additional throttling mechanisms or dynamic prioritization may still be necessary to avoid impacting foreground operations.
-
-# Alternatives
-
-Instead of being triggered by events like Flush or Compact, index building could be performed in batches during scheduled maintenance windows. This offers predictable resource usage but delays index availability.

-# laminar Flow
-
-## Summary
-
-This RFC proposes a redesign of the flow architecture where flownode becomes a lightweight in-memory state management node with an embedded frontend for direct computation. This approach optimizes resource utilization and improves scalability by eliminating network hops while maintaining clear separation between coordination and computation tasks.
-
-## Motivation
-
-The current flow architecture has several limitations:
-
-1. **Resource Inefficiency**: Flownodes perform both state management and computation, leading to resource duplication and inefficient utilization.
-2. **Scalability Constraints**: Computation resources are tied to flownode instances, limiting horizontal scaling capabilities.
-3. **State Management Complexity**: Mixing computation with state management makes the system harder to maintain and debug.
-4. **Network Overhead**: Additional network hops between flownode and separate frontend nodes add latency.
-
-The laminar Flow architecture addresses these issues by:
- Consolidating computation within flownode through embedded frontend
- Eliminating network overhead by removing separate frontend node communication
- Simplifying state management by focusing flownode on its core responsibility
- Improving system scalability and maintainability
-
-## Details
-
-### Architecture Overview
-
-The laminar Flow architecture transforms flownode into a lightweight coordinator that maintains flow state with an embedded frontend for computation. The key components involved are:
-
-1. **Flownode**: Maintains in-memory state, coordinates computation, and includes an embedded frontend for query execution
-2. **Embedded Frontend**: Executes **incremental** computations within the flownode
-3. **Datanode**: Stores final results and source data
-
-```mermaid

-    Coordinator -->|Internal Query| EmbeddedFrontend
-    EmbeddedFrontend -->|Incremental States| Coordinator
-    Flownode -->|Incremental Results| Datanode
-    EmbeddedFrontend -.->|Read Data| Datanode
-```
-
-### Core Components
-
-#### 1. Flow State Management
-
-Flownode maintains a state map for each flow:
-
-```rust
-type FlowState = Map<Timestamp, (Map<Key, Value>, Sequence)>;
-```
-
-Where:
- **Timestamp**: Time window identifier for aggregation groups
- **Key**: Aggregation group expressions (`group_exprs`)
- **Value**: Aggregation expressions results (`aggr_exprs`)
- **Sequence**: Computation progress marker for incremental updates
-
-#### 2. Incremental Computation Process
-
-The computation process follows these steps:
-
-1. **Trigger Evaluation**: Flownode determines when to trigger computation based on:
-   - Time intervals (periodic updates)
-   - Data volume thresholds
-   - Sequence progress requirements
-
-2. **Query Execution**: Flownode executes `__aggr_state` queries using its embedded frontend with:
-   - Time window filters
-   - Sequence range constraints
-
-3. **State Update**: Flownode receives partial state results and updates its internal state:
-   - Merges new values with existing aggregation state
-   - Updates sequence markers to track progress
-   - Identifies changed time windows for result computation
-
-4. **Result Materialization**: Flownode computes final results using `__aggr_merge` operations:
-   - Processes only updated time windows(and time series) for efficiency
-   - Writes results back to datanode directly through its embedded frontend
-
-### Detailed Workflow
-
-#### Incremental State Query
-
-```sql
-- Example incremental state query executed by embedded frontend
-SELECT
-    __aggr_state(avg(value)) as state,
-    time_window,
-    group_key
-FROM source_table
-WHERE
-    timestamp >= :window_start
-    AND timestamp < :window_end
-    AND __sequence >= :last_sequence
-    AND __sequence < :current_sequence
-    -- sequence range is actually written in grpc header, but shown here for clarity
-GROUP BY time_window, group_key;
-```
-
-#### State Merge Process
-
-```mermaid
-sequenceDiagram
-    participant F as Flownode (Coordinator)
-    participant EF as Embedded Frontend (Lightweight)
-    participant DN as Datanode (Heavy Computation)
-    
-    F->>F: Evaluate trigger conditions
-    F->>EF: Execute __aggr_state query with sequence range
-    EF->>DN: Send query to datanode (Heavy scan & aggregation)
-    DN->>DN: Scan data and compute partial aggregation state (Heavy CPU/I/O)
-    DN->>EF: Return aggregated state results
-    EF->>F: Forward state results (Lightweight merge)
-    F->>F: Merge with existing state
-    F->>F: Update sequence markers (Lightweight)
-    F->>EF: Compute incremental results with __aggr_merge
-    EF->>DN: Write incremental results to datanode
-```
-
-### Refill Implementation and State Management
-
-#### Refill Process
-
-Refill is implemented as a straightforward `__aggr_state` query with time and sequence constraints:
-
-```sql
-- Refill query for flow state recovery
-SELECT 
-    __aggr_state(aggregation_functions) as state,
-    time_window,
-    group_keys
-FROM source_table 
-WHERE 
-    timestamp >= :refill_start_time 
-    AND timestamp < :refill_end_time
-    AND __sequence >= :start_sequence 
-    AND __sequence < :end_sequence
-    -- sequence range is actually written in grpc header, but shown here for clarity
-GROUP BY time_window, group_keys;
-```
-
-#### State Recovery Strategy
-
-1. **Recent Data (Stream Mode)**: For recent time windows, flownode refills state using incremental queries
-2. **Historical Data (Batch Mode)**: For older time windows, flownode triggers batch computation directly and no need to refill state
-3. **Hybrid Approach**: Combines stream and batch processing based on data age and availability
-
-#### Mirror Write Optimization
-
-Mirror writes are simplified to only transmit timestamps to flownode:
-
-```rust
-struct MirrorWrite {
-    timestamps: Vec<Timestamp>,
-    // Removed: actual data payload
-}
-```
-
-This optimization:
- Eliminates network overhead by using embedded frontend
- Enables flownode to track pending time windows efficiently
- Allows flownode to decide processing mode (stream vs batch) based on timestamp age
-
-Another optimization could be just send dirty time windows range for each flow to flownode directly, no need to send timestamps one by one.
-
-### Query Optimization Strategies
-
-#### Sequence-Based Incremental Processing
-
-The core optimization relies on sequence-constrained queries:
-
-```sql
-- Optimized incremental query
-SELECT __aggr_state(expr) 
-FROM table 
-WHERE time_range AND sequence_range
-```
-
-Benefits:
- **Reduced Scan Volume**: Only processes data since last computation
- **Efficient Resource Usage**: Minimizes CPU and I/O overhead
- **Predictable Performance**: Query cost scales with incremental data size
-
-#### Time Window Partitioning
-
-```mermaid
-graph LR
-    subgraph "Time Windows"
-        W1["Window 1<br/>09:00-09:05"]
-        W2["Window 2<br/>09:05-09:10"]
-        W3["Window 3<br/>09:10-09:15"]
-    end
-    
-    subgraph "Processing Strategy"
-        W1 --> Batch["Batch Mode<br/>(Old Data)"]
-        W2 --> Stream["Stream Mode<br/>(Recent Data)"]
-        W3 --> Stream2["Stream Mode<br/>(Current Data)"]
-    end
-```
-
-### Performance Characteristics
-
-#### Memory Usage
-
- **Flownode**: O(active_time_windows × group_cardinality) for state storage
- **Embedded Frontend**: O(query_batch_size) for temporary computation
- **Overall**: Significantly reduced compared to current architecture
-
-#### Computation Distribution
-
- **Direct Processing**: Queries processed directly within flownode's embedded frontend
- **Fault Tolerance**: Simplified error handling with fewer distributed components
- **Scalability**: Computation capacity scales with flownode instances
-
-#### Network Optimization
-
- **Reduced Payload**: Mirror writes only contain timestamps
- **Efficient Queries**: Sequence constraints minimize data transfer
- **Result Caching**: State results cached in flownode memory
-
-### Sequential Read Implementation for Incremental Queries
-
-#### Sequence Management
-
-Flow maintains two critical sequences to track incremental query progress for each region:
-
- **`memtable_last_seq`**: Tracks the latest sequence number read from the memtable
- **`sst_last_seq`**: Tracks the latest sequence number read from SST files
-
-These sequences enable precise incremental data processing by defining the exact range of data to query in subsequent iterations.
-
-#### Query Protocol
-
-When executing incremental queries, flownode provides both sequence parameters to datanode:
-
-```rust
-struct GrpcHeader {
-    ...
-    // Sequence tracking for incremental reads
-    memtable_last_seq: HashMap<RegionId, SequenceNumber>,
-    sst_last_seqs: HashMap<RegionId, SequenceNumber>,
-}
-```
-
-The datanode processes these parameters to return only the data within the specified sequence ranges, ensuring efficient incremental processing.
-
-#### Sequence Invalidation and Refill Mechanism
-
-A critical challenge occurs when data referenced by `memtable_last_seq` gets flushed from memory to disk. Since SST files only maintain a single maximum sequence number for the entire file (rather than per-record sequence tracking), precise incremental queries become impossible for the affected time ranges.
-
-**Detection of Invalidation:**
-```rust
-// When memtable_last_seq data has been flushed to SST
-if memtable_last_seq_flushed_to_disk {
-    // Incremental query is no longer feasible
-    // Need to trigger refill for affected time ranges
-}
-```
-
-**Refill Process:**
-1. **Identify Affected Time Range**: Query the time range corresponding to the flushed `memtable_last_seq` data
-2. **Full Recomputation**: Execute a complete aggregation query for the affected time windows
-3. **State Replacement**: Replace the existing flow state for these time ranges with newly computed values
-4. **Sequence Update**: Update `memtable_last_seq` to the current latest sequence, while `sst_last_seq` continues normal incremental updates
-
-```sql
-- Refill query when memtable data has been flushed
-SELECT
-    __aggr_state(aggregation_functions) as state,
-    time_window,
-    group_keys
-FROM source_table
-WHERE
-    timestamp >= :affected_time_start
-    AND timestamp < :affected_time_end
-    -- Full scan required since sequence precision is lost in SST
-GROUP BY time_window, group_keys;
-```
-
-#### Datanode Implementation Requirements
-
-Datanode must implement enhanced query processing capabilities to support sequence-based incremental reads:
-
-**Input Processing:**
- Accept `memtable_last_seq` and `sst_last_seq` parameters in query requests
- Filter data based on sequence ranges across both memtable and SST storage layers
-
-**Output Enhancement:**
-```rust
-struct OutputMeta {
-    pub plan: Option<Arc<dyn ExecutionPlan>>,
-    pub cost: OutputCost,
-    pub sequence_info: HashMap<RegionId, SequenceInfo>, // New field for sequence tracking per regions involved in the query
-}
-
-struct SequenceInfo {
-    // Sequence tracking for next iteration
-    max_memtable_seq: SequenceNumber,  // Highest sequence from memtable in this result
-    max_sst_seq: SequenceNumber,       // Highest sequence from SST in this result
-}
-```
-
-**Sequence Tracking Logic:**
-datanode already impl `max_sst_seq` in leader range read, can reuse similar logic for `max_memtable_seq`.
-
-#### Sequence Update Strategy
-
-**Normal Incremental Updates:**
- Update both `memtable_last_seq` and `sst_last_seq` after successful query execution
- Use returned `max_memtable_seq` and `max_sst_seq` values for next iteration
-
-**Refill Scenario:**
- Reset `memtable_last_seq` to current maximum after refill completion
- Continue normal `sst_last_seq` updates based on successful query responses
- Maintain separate tracking to detect future flush events
-
-#### Performance Considerations
-
-**Sequence Range Optimization:**
- Minimize sequence range spans to reduce scan overhead
- Batch multiple small incremental updates when beneficial
- Balance between query frequency and processing efficiency
-
-**Memory Management:**
- Monitor memtable flush frequency to predict refill requirements
- Implement adaptive query scheduling based on flush patterns
- Optimize state storage to handle frequent updates efficiently
-
-This sequential read implementation ensures reliable incremental processing while gracefully handling the complexities of storage architecture, maintaining both correctness and performance in the face of background compaction and flush operations.
-
-## Implementation Plan
-
-### Phase 1: Core Infrastructure
-
-1. **State Management**: Implement in-memory state map in flownode
-2. **Query Interface**: Integrate `__aggr_state` query interface in embedded frontend(Already done in previous query pushdown optimizer work)
-3. **Basic Coordination**: Implement query dispatch and result collection
-4. **Sequence Tracking**: Implement sequence-based incremental processing(Can use similar interface which leader range read use)
-
-After phase 1, the system should support basic flow operations with incremental updates.
-
-### Phase 2: Optimization Features
-
-1. **Refill Logic**: Develop state recovery mechanisms
-2. **Mirror Write Optimization**: Simplify mirror write protocol
-
-### Phase 3: Advanced Features
-
-1. **Load Balancing**: Implement intelligent resource allocation for partitioned flow(Flow distributed executed on multiple flownodes)
-2. **Fault Tolerance**: Add retry mechanisms and error handling
-3. **Performance Tuning**: Optimize query batching and state management
-
-## Drawbacks
-
-### Reduced Network Communication
-
- **Eliminated Hops**: Direct communication between flownode and datanode through embedded frontend
- **Reduced Latency**: No separate frontend node communication overhead
- **Simplified Network Topology**: Fewer network dependencies and failure points
-
-### Complexity in Error Handling
-
- **Distributed Failures**: Need to handle failures across multiple components
- **State Consistency**: Ensuring state consistency during partial failures
- **Recovery Complexity**: More complex recovery procedures
-
-### Datanode Resource Requirements
-
- **Computation Load**: Datanode handles the heavy computational workload for flow queries
- **Query Interference**: Flow queries may impact regular query performance on datanode
- **Resource Contention**: Need careful resource management and isolation on datanode
-
-## Alternatives
-
-### Alternative 1: Enhanced Current Architecture
-
-Keep computation in flownode but optimize through:
- Better resource management
- Improved query optimization
- Enhanced state persistence
-
-**Pros:**
- Simpler architecture
- Fewer network hops
- Easier debugging
-
-**Cons:**
- Limited scalability
- Resource inefficiency
- Harder to optimize computation distribution
-
-### Alternative 2: Embedded Computation
-
-Embed lightweight computation engines within flownode:
-
-**Pros:**
- Reduced network communication
- Better performance for simple queries
- Simpler deployment
-
-**Cons:**
- Limited scalability
- Resource constraints
- Harder to leverage existing frontend optimizations
-
-## Future Work
-
-### Advanced Query Optimization
-
- **Parallel Processing**: Enable parallel execution of flow queries
- **Query Caching**: Cache frequently executed query patterns
-
-### Enhanced State Management
-
- **State Compression**: Implement efficient state serialization
- **Distributed State**: Support state distribution across multiple flownodes
- **State Persistence**: Add optional state persistence for durability
-
-### Monitoring and Observability
-
- **Performance Metrics**: Track query execution times and resource usage
- **State Visualization**: Provide tools for state inspection and debugging
- **Health Monitoring**: Monitor system health and performance characteristics
-
-### Integration Improvements
-
- **Embedded Frontend Optimization**: Optimize embedded frontend query planning and execution
- **Datanode Optimization**: Optimize result writing from flownode
- **Metasrv Coordination**: Enhanced metadata management and coordination
-
-## Conclusion
-
-The laminar Flow architecture represents a significant improvement over the current flow system by separating state management from computation execution. This design enables better resource utilization, improved scalability, and simplified maintenance while maintaining the core functionality of continuous aggregation.
-
-The key benefits include:
-
-1. **Improved Scalability**: Computation can scale independently of state management
-2. **Better Resource Utilization**: Eliminates network overhead and leverages embedded frontend infrastructure
-3. **Simplified Architecture**: Clear separation of concerns between components
-4. **Enhanced Performance**: Sequence-based incremental processing reduces computational overhead
-
-While the architecture introduces some complexity in terms of distributed coordination and error handling, the benefits significantly outweigh the drawbacks, making it a compelling evolution of the flow system.

-# Grafana dashboards for GreptimeDB
+Grafana dashboard for GreptimeDB
+--------------------------------

-## Overview
+GreptimeDB's official Grafana dashboard.

-This repository contains Grafana dashboards for visualizing metrics and logs of GreptimeDB instances running in either cluster or standalone mode. **The Grafana version should be greater than 9.0**.
+Status notify: we are still working on this config. It's expected to change frequently in the recent days. Please feel free to submit your feedback and/or contribution to this dashboard 🤗

-We highly recommend using the self-monitoring feature provided by [GreptimeDB Operator](https://github.com/GrepTimeTeam/greptimedb-operator) to automatically collect metrics and logs from your GreptimeDB instances and store them in a dedicated GreptimeDB instance.
-
- **Metrics Dashboards**
-
-  - `dashboards/metrics/cluster/dashboard.json`: The Grafana dashboard for the GreptimeDB cluster. Read the [dashboard.md](./dashboards/metrics/cluster/dashboard.md) for more details.
-
-  - `dashboards/metrics/standalone/dashboard.json`: The Grafana dashboard for the standalone GreptimeDB instance. **It's generated from the `cluster/dashboard.json` by removing the instance filter through the `make dashboards` command**. Read the [dashboard.md](./dashboards/metrics/standalone/dashboard.md) for more details.
-
- **Logs Dashboard**
-
-  The `dashboards/logs/dashboard.json` provides a comprehensive Grafana dashboard for visualizing GreptimeDB logs. To utilize this dashboard effectively, you need to collect logs in JSON format from your GreptimeDB instances and store them in a dedicated GreptimeDB instance.
-
-  For proper integration, the logs table must adhere to the following schema design with the table name `_gt_logs`:
-
-  ```sql
-  CREATE TABLE IF NOT EXISTS `_gt_logs` (
-    `pod_ip` STRING NULL,
-    `namespace` STRING NULL,
-    `cluster` STRING NULL,
-    `file` STRING NULL,
-    `module_path` STRING NULL,
-    `level` STRING NULL,
-    `target` STRING NULL,
-    `role` STRING NULL,
-    `pod` STRING NULL SKIPPING INDEX WITH(granularity = '10240', type = 'BLOOM'),
-    `message` STRING NULL FULLTEXT INDEX WITH(analyzer = 'English', backend = 'bloom', case_sensitive = 'false'),
-    `err` STRING NULL FULLTEXT INDEX WITH(analyzer = 'English', backend = 'bloom', case_sensitive = 'false'),
-    `timestamp` TIMESTAMP(9) NOT NULL,
-    TIME INDEX (`timestamp`),
-    PRIMARY KEY (`level`, `target`, `role`)
-  )
-    ENGINE=mito
-  WITH (
-    append_mode = 'true'
-  )
-  ```
-
-## Development
-
-As GreptimeDB evolves rapidly, metrics may change over time. We welcome your feedback and contributions to improve these dashboards 🤗
-
-To modify the metrics dashboards, simply edit the `dashboards/metrics/cluster/dashboard.json` file and run the `make dashboards` command. This will automatically generate the updated `dashboards/metrics/standalone/dashboard.json` and other related files.
-
-For easier dashboard maintenance, we utilize the [`dac`](https://github.com/zyy17/dac) tool to generate human-readable intermediate dashboards and documentation:
-
- `dashboards/metrics/cluster/dashboard.yaml`: The intermediate dashboard file for the GreptimeDB cluster.
- `dashboards/metrics/standalone/dashboard.yaml`: The intermediate dashboard file for standalone GreptimeDB instances.
-
-## Data Sources
-
-The following data sources are used to fetch metrics and logs:
-
- **`${metrics}`**: Prometheus data source for providing the GreptimeDB metrics.
- **`${logs}`**: MySQL data source for providing the GreptimeDB logs.
- **`${information_schema}`**: MySQL data source for providing the information schema of the current instance and used for the `overview` panel. It is the MySQL port of the current monitored instance.
-
-## Instance Filters
-
-To deploy the dashboards for multiple scenarios (K8s, bare metal, etc.), we prefer to use the `instance` label when filtering instances.
-
-Additionally, we recommend including the `pod` label in the legend to make it easier to identify each instance, even though this field will be empty in bare metal scenarios.
-
-For example, the following query is recommended:
-
-```promql
-sum(process_resident_memory_bytes{instance=~"$datanode"}) by (instance, pod)
-```
-
-And the legend will be like: `[{{instance}}]-[{{ pod }}]`.
-
-## Deployment
-
-### (Recommended) Helm Chart
-
-If you use the [Helm Chart](https://github.com/GreptimeTeam/helm-charts) to deploy a GreptimeDB cluster, you can enable self-monitoring by setting the following values in your Helm chart:
+If you use Helm [chart](https://github.com/GreptimeTeam/helm-charts) to deploy GreptimeDB cluster, you can enable self-monitoring by setting the following values in your Helm chart:

 - `monitoring.enabled=true`: Deploys a standalone GreptimeDB instance dedicated to monitoring the cluster;
 - `grafana.enabled=true`: Deploys Grafana and automatically imports the monitoring dashboard;

-The standalone GreptimeDB instance will collect metrics from your cluster, and the dashboard will be available in the Grafana UI. For detailed deployment instructions, please refer to our [Kubernetes deployment guide](https://docs.greptime.com/user-guide/deployments-administration/deploy-on-kubernetes/overview).

-### Self-host Prometheus and import dashboards manually
+# How to use

-1. **Configure Prometheus to scrape the cluster**
+## `greptimedb.json`

-   The following is an example configuration(**Please modify it according to your actual situation**):
+Open Grafana Dashboard page, choose `New` -> `Import`. And upload `greptimedb.json` file.

-    ```yml
-    # example config
-    # only to indicate how to assign labels to each target
-    # modify yours accordingly
-    scrape_configs:
-      - job_name: metasrv
-        static_configs:
-        - targets: ['<metasrv-ip>:<port>']
+## `greptimedb-cluster.json`

-      - job_name: datanode
-        static_configs:
-        - targets: ['<datanode0-ip>:<port>', '<datanode1-ip>:<port>', '<datanode2-ip>:<port>']
+This cluster dashboard provides a comprehensive view of incoming requests, response statuses, and internal activities such as flush and compaction, with a layered structure from frontend to datanode. Designed with a focus on alert functionality, its primary aim is to highlight any anomalies in metrics, allowing users to quickly pinpoint the cause of errors.

-      - job_name: frontend
-        static_configs:
-        - targets: ['<frontend-ip>:<port>']
-    ```
+We use Prometheus to scrape off metrics from nodes in GreptimeDB cluster, Grafana to visualize the diagram. Any compatible stack should work too.

-2. **Configure the data sources in Grafana**
+__Note__: This dashboard is still in an early stage of development. Any issue or advice on improvement is welcomed.

-   You need to add two data sources in Grafana:
+### Configuration

-   - Prometheus: It is the Prometheus instance that scrapes the GreptimeDB metrics.
-   - Information Schema: It is the MySQL port of the current monitored instance. The dashboard will use this datasource to show the information schema of the current instance.
+Please ensure the following configuration before importing the dashboard into Grafana.

-3. **Import the dashboards based on your deployment scenario**
+__1. Prometheus scrape config__

-   - **Cluster**: Import the `dashboards/metrics/cluster/dashboard.json` dashboard.
-   - **Standalone**: Import the `dashboards/metrics/standalone/dashboard.json` dashboard.
+Configure Prometheus to scrape the cluster.
+
+```yml
+# example config
+# only to indicate how to assign labels to each target
+# modify yours accordingly
+scrape_configs:
+  - job_name: metasrv
+    static_configs:
+    - targets: ['<metasrv-ip>:<port>']
+
+  - job_name: datanode
+    static_configs:
+    - targets: ['<datanode0-ip>:<port>', '<datanode1-ip>:<port>', '<datanode2-ip>:<port>']
+
+  - job_name: frontend
+    static_configs:
+    - targets: ['<frontend-ip>:<port>']
+```
+
+__2. Grafana config__
+
+Create a Prometheus data source in Grafana before using this dashboard. We use `datasource` as a variable in Grafana dashboard so that multiple environments are supported.
+
+### Usage
+
+Use `datasource` or `instance` on the upper-left corner to filter data from certain node.
