docs/how-to/how-to-write-aggregate-function.md

@@ -1,72 +0,0 @@
-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/datafusion/tree/main/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 preferred 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 find a way to bypass DataFusion's restriction, a restriction that DataFusion simply doesn'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 be 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, its 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 your 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 executes 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 calculate, 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 wants to let everyone use it, you can make it automatically register to our query engine at start time. It's quick and simple, just refer to the `AggregateFunctions::register` function in `common/function/src/scalars/aggregate/mod.rs`.

+Feature Name: Async Index Build
+Tracking Issue: https://github.com/GreptimeTeam/greptimedb/issues/6756
+Date: 2025-08-16
+Author: "SNC123 <sinhco@outlook.com>"
+---
+
+# 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.
