### Added Deduplication and Merge Functionality

- Introduced `DedupReader` and `MergeReader` in `src/mito2/src/read/sync/dedup.rs` and `src/mito2/src/read/sync/merge.rs` to handle deduplication and merging of sorted batches.
 ### Enhanced `BulkMemtable` Iteration
 - Updated `BulkMemtable` in `src/mito2/src/memtable/bulk.rs` to support deduplication and merge modes during iteration.
 - Added `BulkIterContext` to manage iteration context.
 ### Testing Enhancements
 - Added comprehensive tests for `BulkMemtable` and `BulkPart` in `src/mito2/src/memtable/bulk.rs` and `src/mito2/src/memtable/bulk/part.rs`.
 ### Code Refactoring
 - Made `BulkPart` and `BulkPartMeta` cloneable in `src/mito2/src/memtable/bulk/part.rs`.
 - Exposed internal test modules for better test coverage in `src/mito2/src/memtable/time_series.rs` and `src/mito2/src/read/merge.rs`.
 ### New Modules
 - Created `sync` module in `src/mito2/src/read.rs` to organize synchronous read operations.

 ## Introduction
 
-**GreptimeDB** is an open-source time-series database focusing on efficiency, scalability, and analytical capabilities.
+**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.
-Designed to work on infrastructure of the cloud era, GreptimeDB benefits users with its elasticity and commodity storage, offering a fast and cost-effective **alternative to InfluxDB** and a **long-term storage for Prometheus**.
 
 ## Why GreptimeDB
 
-Our core developers have been building time-series data platforms for years. Based on our best-practices, GreptimeDB is born to give you:
+Our core developers have been building time-series data platforms for years. Based on our best practices, GreptimeDB was born to give you:
 
-* **Easy horizontal scaling**
+* **Unified Processing of Metrics, Logs, and Events**
 
-  Seamless scalability from a standalone binary at edge to a robust, highly available distributed cluster in cloud, with a transparent experience for both developers and administrators.
+  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. [Read more](https://docs.greptime.com/user-guide/concepts/data-model).
 
-* **Analyzing time-series data**
+* **Cloud-native Distributed Database**
 
-  Query your time-series data with SQL and PromQL. Use Python scripts to facilitate complex analytical tasks.
+  Built for [Kubernetes](https://docs.greptime.com/user-guide/deployments/deploy-on-kubernetes/greptimedb-operator-management). GreptimeDB achieves seamless scalability with its [cloud-native architecture](https://docs.greptime.com/user-guide/concepts/architecture) of separated compute and storage, built on object storage (AWS S3, Azure Blob Storage, etc.) while enabling cross-cloud deployment through a unified data access layer.
-
-* **Cloud-native distributed database**
-
-  Fully open-source distributed cluster architecture that harnesses the power of cloud-native elastic computing resources.
 
 * **Performance and Cost-effective**
 
-  Flexible indexing capabilities and distributed, parallel-processing query engine, tackling high cardinality issues down. Optimized columnar layout for handling time-series data; compacted, compressed, and stored on various storage backends, particularly cloud object storage with 50x cost efficiency.
+  Written in pure Rust for superior performance and reliability. GreptimeDB features a distributed query engine with intelligent indexing to handle high cardinality data efficiently. Its optimized columnar storage achieves 50x cost efficiency on cloud object storage through advanced compression. [Benchmark reports](https://www.greptime.com/blogs/2024-09-09-report-summary).
 
-* **Compatible with InfluxDB, Prometheus and more protocols**
+* **Cloud-Edge Collaboration**
 
-  Widely adopted database protocols and APIs, including MySQL, PostgreSQL, and Prometheus Remote Storage, etc. [Read more](https://docs.greptime.com/user-guide/clients/overview).
+  GreptimeDB seamlessly operates across cloud and edge (ARM/Android/Linux), providing consistent APIs and control plane for unified data management and efficient synchronization. [Learn how to run on Android](https://docs.greptime.com/user-guide/deployments/run-on-android/).
+
+* **Multi-protocol Ingestion, SQL & PromQL Ready**
+
+  Widely adopted database protocols and APIs, including MySQL, PostgreSQL, InfluxDB, OpenTelemetry, Loki and Prometheus, etc.  Effortless Adoption & Seamless Migration. [Supported Protocols Overview](https://docs.greptime.com/user-guide/protocols/overview).

-Benchmarkers for GreptimeDB
---------------------------------
-
-## Wal Benchmarker
-The wal benchmarker serves to evaluate the performance of GreptimeDB's Write-Ahead Log (WAL) component. It meticulously assesses the read/write performance of the WAL under diverse workloads generated by the benchmarker. 
-
-
-### How to use
-To compile the benchmarker, navigate to the `greptimedb/benchmarks` directory and execute `cargo build --release`. Subsequently, you'll find the compiled target located at `greptimedb/target/release/wal_bench`.
-
-The `./wal_bench -h` command reveals numerous arguments that the target accepts. Among these, a notable one is the `cfg-file` argument. By utilizing a configuration file in the TOML format, you can bypass the need to repeatedly specify cumbersome arguments.

+# Log benchmark configuration
+This repo holds the configuration we used to benchmark GreptimeDB, Clickhouse and Elastic Search.
+
+Here are the versions of databases we used in the benchmark
+
+| name          | version    |
+| :------------ | :--------- |
+| GreptimeDB    | v0.9.2     |
+| Clickhouse    | 24.9.1.219 |
+| Elasticsearch | 8.15.0     |
+
+## Structured model vs Unstructured model
+We divide test into two parts, using structured model and unstructured model accordingly. You can also see the difference in create table clause.
+
+__Structured model__
+
+The log data is pre-processed into columns by vector. For example an insert request looks like following
+```SQL
+INSERT INTO test_table (bytes, http_version, ip, method, path, status, user, timestamp) VALUES ()
+```
+The goal is to test string/text support for each database. In real scenarios it means the datasource(or log data producers) have separate fields defined, or have already processed the raw input.
+
+__Unstructured model__
+
+The log data is inserted as a long string, and then we build fulltext index upon these strings. For example an insert request looks like following
+```SQL
+INSERT INTO test_table (message, timestamp) VALUES ()
+```
+The goal is to test fuzzy search performance for each database. In real scenarios it means the log is produced by some kind of middleware and inserted directly into the database.
+
+## Creating tables
+See [here](./create_table.sql) for GreptimeDB and Clickhouse's create table clause.
+The mapping of Elastic search is created automatically.
+
+## Vector Configuration
+We use vector to generate random log data and send inserts to databases.
+Please refer to [structured config](./structured_vector.toml) and [unstructured config](./unstructured_vector.toml) for detailed configuration.
+
+## SQLs and payloads
+Please refer to [SQL query](./query.sql) for GreptimeDB and Clickhouse, and [query payload](./query.md) for Elastic search.
+
+## Steps to reproduce
+0. Decide whether to run structured model test or unstructured mode test.
+1. Build vector binary(see vector's config file for specific branch) and databases binaries accordingly.
+2. Create table in GreptimeDB and Clickhouse in advance.
+3. Run vector to insert data.
+4. When data insertion is finished, run queries against each database. Note: you'll need to update timerange value after data insertion.
+
+## Addition
+- You can tune GreptimeDB's configuration to get better performance.
+- You can setup GreptimeDB to use S3 as storage, see [here](https://docs.greptime.com/user-guide/deployments/configuration#storage-options).

+# How to run TSBS Benchmark
+
+This document contains the steps to run TSBS Benchmark. Our results are listed in other files in the same directory.
+
+## Prerequires
+
+You need the following tools to run TSBS Benchmark:
+- Go
+- git
+- make
+- rust (optional, if you want to build the DB from source)
+
+## Build TSBS suite
+
+Clone our fork of TSBS:
+
+```shell
+git clone https://github.com/GreptimeTeam/tsbs.git
+```
+
+Then build it:
+
+```shell
+cd tsbs
+make
+```
+
+You can check the `bin/` directory for compiled binaries. We will only use some of them.
+
+```shell
+ls ./bin/
+```
+
+Binaries we will use later:
+- `tsbs_generate_data`
+- `tsbs_generate_queries`
+- `tsbs_load_greptime`
+- `tsbs_run_queries_influx`
+
+## Generate test data and queries
+
+The data is generated by `tsbs_generate_data`
+
+```shell
+mkdir bench-data
+./bin/tsbs_generate_data --use-case="cpu-only" --seed=123 --scale=4000 \
+    --timestamp-start="2023-06-11T00:00:00Z" \
+    --timestamp-end="2023-06-14T00:00:00Z" \
+    --log-interval="10s" --format="influx" \
+    > ./bench-data/influx-data.lp
+```
+
+Here we generates 4000 time-series in 3 days with 10s interval. We'll use influx line protocol to write so the target format is `influx`.
+
+Queries are generated by `tsbs_generate_queries`. You can change the parameters but need to make sure it matches with `tsbs_generate_data`.
+
+```shell
+./bin/tsbs_generate_queries \
+    --use-case="devops" --seed=123 --scale=4000 \
+    --timestamp-start="2023-06-11T00:00:00Z" \

+
+## Start GreptimeDB
+
+Reference to our [document](https://docs.greptime.com/getting-started/installation/overview) for how to install and start a GreptimeDB. Or you can also check this [document](https://docs.greptime.com/contributor-guide/getting-started#compile-and-run) for how to build a GreptimeDB from source.
+
+## Write Data
+
+After the DB is started, we can use `tsbs_load_greptime` to test the write performance.
+
+```shell
+./bin/tsbs_load_greptime \
+    --urls=http://localhost:4000 \
+    --file=./bench-data/influx-data.lp \
+    --batch-size=3000 \
+    --gzip=false \
+    --workers=6
+```
+
+Parameters here are only provided as an example. You can choose whatever you like or adjust them to match your target scenario.
+
+Notice that if you want to rerun `tsbs_load_greptime`, please destroy and restart the DB and clear its previous data first. Existing duplicated data will impact the write and query performance.
+
+## Query Data
+
+After the data is imported, you can then run queries. The following script runs all queries. You can also choose a subset of queries to run.
+
+```shell
+./bin/tsbs_run_queries_influx --file=./bench-data/greptime-queries-cpu-max-all-1.dat \
+    --db-name=benchmark \

+Feature Name: Json Datatype

+Date: 2024-8-6
+Author: "Yuhan Wang <profsyb@gmail.com>"

+
+# Summary
+This RFC proposes a method for storing and querying JSON data in the database.
+
+# Motivation
+JSON is widely used across various scenarios. Direct support for writing and querying JSON can significantly enhance the database's flexibility.
+
+# Details
+
+## Storage and Query
+
+GreptimeDB's type system is built on Arrow/DataFusion, where each data type in GreptimeDB corresponds to a data type in Arrow/DataFusion. The proposed JSON type will be implemented on top of the existing `Binary` type, leveraging the current `datatype::value::Value` and `datatype::vectors::BinaryVector` implementations, utilizing the JSONB format as the encoding of JSON data. JSON data is stored and processed similarly to binary data within the storage layer and query engine.
+
+This approach brings problems when dealing with insertions and queries of JSON columns.
+
+## Insertion
+
+Users commonly write JSON data as strings. Thus we need to make conversions between string and JSONB. There are 2 ways to do this:
+
+1. MySQL and PostgreSQL servers provide auto-conversions between strings and JSONB. When a string is inserted into a JSON column, the server will try to parse the string as JSON and convert it to JSONB. The non-JSON strings will be rejected.
+
+2. A function `parse_json` is provided to convert string to JSONB. If the string is not a valid JSON string, the function will return an error.
+
+For example, in MySQL client:
+```SQL
+CREATE TABLE IF NOT EXISTS test (
+    ts TIMESTAMP TIME INDEX,
+    a INT,
+    b JSON
+);
+
+INSERT INTO test VALUES(
+    0,
+    0,
+    '{
+        "name": "jHl2oDDnPc1i2OzlP5Y",
+        "timestamp": "2024-07-25T04:33:11.369386Z",
+        "attributes": { "event_attributes": 48.28667 }
+    }'
+);
+
+INSERT INTO test VALUES(
+    0,
+    0,
+    parse_json('{
+        "name": "jHl2oDDnPc1i2OzlP5Y",
+        "timestamp": "2024-07-25T04:33:11.369386Z",
+        "attributes": { "event_attributes": 48.28667 }
+    }')
+);
+```
+Are both valid.
+
+The dataflow of the insertion process is as follows:
+```
+Insert JSON strings directly through client:
+                                   Parse                       Insert
+        String(Serialized JSON)┌──────────┐Arrow Binary(JSONB)┌──────┐Arrow Binary(JSONB)
+ Client ---------------------->│  Server  │------------------>│ Mito │------------------> Storage
+                               └──────────┘                   └──────┘
+        (Server identifies JSON type and performs auto-conversion)
+
+Insert JSON strings through parse_json function:
+                                                                   Parse                     Insert
+        String(Serialized JSON)┌──────────┐String(Serialized JSON)┌─────┐Arrow Binary(JSONB)┌──────┐Arrow Binary(JSONB)
+ Client ---------------------->│  Server  │---------------------->│ UDF │------------------>│ Mito │------------------> Storage
+                               └──────────┘                       └─────┘                   └──────┘
+                                            (Conversion is performed by UDF inside Query Engine)
+```
+
+Servers identify JSON column through column schema and perform auto-conversions. But when using prepared statements and binding parameters, the corresponding cached plans in datafusion generated by prepared statements cannot identify JSON columns. Under this circumstance, the servers identify JSON columns through the given parameters and perform auto-conversions.
+
+The following is an example of inserting JSON data through prepared statements:
+```Rust
+sqlx::query(
+    "create table test(ts timestamp time index, j json)",
+)
+.execute(&pool)
+.await
+.unwrap();
+
+let json = serde_json::json!({
+    "code": 200,
+    "success": true,
+    "payload": {
+        "features": [
+            "serde",
+            "json"
+        ],
+        "homepage": null
+    }
+});
+
+// Valid, can identify serde_json::Value as JSON type
+sqlx::query("insert into test values($1, $2)")
+    .bind(i)
+    .bind(json)
+    .execute(&pool)
+    .await
+    .unwrap();
+
+// Invalid, cannot identify String as JSON type
+sqlx::query("insert into test values($1, $2)")
+    .bind(i)
+    .bind(json.to_string())
+    .execute(&pool)
+    .await
+    .unwrap();
+```
+
+## Query
+
+Correspondingly, users prefer to display JSON data as strings. Thus we need to make conversions between JSON data and strings before presenting JSON data. There are also 2 ways to do this: auto-conversions on MySQL and PostgreSQL servers, and function `json_to_string`.
+
+For example, in MySQL client:
+```SQL
+SELECT b FROM test;
+
+SELECT json_to_string(b) FROM test;
+```
+Will both return the JSON as human-readable strings.
+
+Specifically, to perform auto-conversions, we attach a message to JSON data in the `metadata` of `Field` in Arrow/Datafusion schema when scanning a JSON column. Frontend servers could identify JSON data and convert it to strings.
+
+The dataflow of the query process is as follows:
+```
+Query directly through client:
+                                  Decode                            Scan
+        String(Serialized JSON)┌──────────┐Arrow Binary(JSONB)┌──────────────┐Arrow Binary(JSONB)
+ Client <----------------------│  Server  │<------------------│ Query Engine │<----------------- Storage
+                               └──────────┘                   └──────────────┘
+(Server identifies JSON type and performs auto-conversion based on column metadata)
+
+Query through json_to_string function:
+                                                                   Scan & Decode
+        String(Serialized JSON)┌──────────┐String(Serialized JSON)┌──────────────┐Arrow Binary(JSONB)
+ Client <----------------------│  Server  │<----------------------│ Query Engine │<----------------- Storage
+                               └──────────┘                       └──────────────┘
+                                                 (Conversion is performed by UDF inside Query Engine)
+
+```
+
+However, if a function uses JSON type as its return type, the metadata method mentioned above is not applicable. Thus the functions of JSON type should specify the return type explicitly instead of returning a JSON type, such as `json_get_int` and `json_get_float` which return corresponding data of `INT` and `FLOAT` type respectively.
+
+## Functions
+Similar to the common JSON type, JSON data can be queried with functions.
+
+For example:
+```SQL
+CREATE TABLE IF NOT EXISTS test (
+    ts TIMESTAMP TIME INDEX,
+    a INT,
+    b JSON
+);
+
+INSERT INTO test VALUES(
+    0,
+    0,
+    '{
+        "name": "jHl2oDDnPc1i2OzlP5Y",
+        "timestamp": "2024-07-25T04:33:11.369386Z",
+        "attributes": { "event_attributes": 48.28667 }
+    }'
+);
+
+SELECT json_get_string(b, 'name') FROM test;
++---------------------+
+| b.name              |
++---------------------+
+| jHl2oDDnPc1i2OzlP5Y |
++---------------------+
+
+SELECT json_get_float(b, 'attributes.event_attributes') FROM test;
++--------------------------------+
+| b.attributes.event_attributes  |
++--------------------------------+
+| 48.28667                       |
++--------------------------------+
+
+```
+And more functions can be added in the future.
+
+# Drawbacks
+
+As a general purpose JSON data type, JSONB may not be as efficient as specialized data types for specific scenarios.
+
+The auto-conversion mechanism is not supported in all scenarios. We need to find workarounds for these scenarios.
+
+# Alternatives
+
+Extract and flatten JSON schema to store in a structured format through pipeline. For nested data, we can provide nested types like `STRUCT` or `ARRAY`.

-# Schema Structs

-# Common Schemas
-The `datatypes` crate defines the elementary schema struct to describe the metadata.
-
-## ColumnSchema
-[ColumnSchema](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/datatypes/src/schema/column_schema.rs#L36) represents the metadata of a column. It is equivalent to arrow's [Field](https://docs.rs/arrow/latest/arrow/datatypes/struct.Field.html) with additional metadata such as default constraint and whether the column is a time index. The time index is the column with a `TIME INDEX` constraint of a table. We can convert the `ColumnSchema` into an arrow `Field` and convert the `Field` back to the `ColumnSchema` without losing metadata.
-
-```rust
-pub struct ColumnSchema {
-    pub name: String,
-    pub data_type: ConcreteDataType,
-    is_nullable: bool,
-    is_time_index: bool,
-    default_constraint: Option<ColumnDefaultConstraint>,
-    metadata: Metadata,
-}
-```
-
-## Schema
-[Schema](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/datatypes/src/schema.rs#L38) is an ordered sequence of `ColumnSchema`. It is equivalent to arrow's [Schema](https://docs.rs/arrow/latest/arrow/datatypes/struct.Schema.html) with additional metadata including the index of the time index column and the version of this schema. Same as `ColumnSchema`, we can convert our `Schema` from/to arrow's `Schema`.
-
-```rust
-use arrow::datatypes::Schema as ArrowSchema;
-
-pub struct Schema {
-    column_schemas: Vec<ColumnSchema>,
-    name_to_index: HashMap<String, usize>,
-    arrow_schema: Arc<ArrowSchema>,
-    timestamp_index: Option<usize>,
-    version: u32,
-}
-
-pub type SchemaRef = Arc<Schema>;
-```
-
-We alias `Arc<Schema>` as `SchemaRef` since it is used frequently. Mostly, we use our `ColumnSchema` and `Schema` structs instead of Arrow's `Field` and `Schema` unless we need to invoke third-party libraries (like DataFusion or ArrowFlight) that rely on Arrow.
-
-## RawSchema
-`Schema` contains fields like a map from column names to their indices in the `ColumnSchema` sequences and a cached arrow `Schema`. We can construct these fields from the `ColumnSchema` sequences thus we don't want to serialize them. This is why we don't derive `Serialize` and `Deserialize` for `Schema`. We introduce a new struct [RawSchema](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/datatypes/src/schema/raw.rs#L24) which keeps all required fields of a `Schema` and derives the serialization traits. To serialize a `Schema`, we need to convert it into a `RawSchema` first and serialize the `RawSchema`.
-
-```rust
-pub struct RawSchema {
-    pub column_schemas: Vec<ColumnSchema>,
-    pub timestamp_index: Option<usize>,
-    pub version: u32,
-}
-```
-
-We want to keep the `Schema` simple and avoid putting too much business-related metadata in it as many different structs or traits rely on it.
-
-# Schema of the Table
-A table maintains its schema in [TableMeta](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/table/src/metadata.rs#L97).
-```rust
-pub struct TableMeta {
-    pub schema: SchemaRef,
-    pub primary_key_indices: Vec<usize>,
-    pub value_indices: Vec<usize>,
-    // ...
-}
-```
-
-The order of columns in `TableMeta::schema` is the same as the order specified in the `CREATE TABLE` statement which users use to create this table.
-
-The field `primary_key_indices` stores indices of primary key columns. The field `value_indices` records the indices of value columns (non-primary key and time index, we sometimes call them field columns).
-
-Suppose we create a table with the following SQL
-```sql
-CREATE TABLE cpu (
-    ts TIMESTAMP,
-    host STRING,
-    usage_user DOUBLE,
-    usage_system DOUBLE,
-    datacenter STRING,
-    TIME INDEX (ts),
-    PRIMARY KEY(datacenter, host)) ENGINE=mito;
-```
-
-Then the table's `TableMeta` may look like this:
-```json
-{
-    "schema":{
-        "column_schemas":[
-            "ts",
-            "host",
-            "usage_user",
-            "usage_system",
-            "datacenter"
-        ],
-        "time_index":0,
-        "version":0
-    },
-    "primary_key_indices":[
-        4,
-        1
-    ],
-    "value_indices":[
-        2,
-        3
-    ]
-}
-```
-
-
-# Schemas of the storage engine
-We split a table into one or more units with the same schema and then store these units in the storage engine. Each unit is a region in the storage engine.
-
-The storage engine maintains schemas of regions in more complicated ways because it
-- adds internal columns that are invisible to users to store additional metadata for each row
-- provides a data model similar to the key-value model so it organizes columns in a different order
-- maintains additional metadata like column id or column family
-
-So the storage engine defines several schema structs:
-- RegionSchema
-- StoreSchema
-- ProjectedSchema
-
-## RegionSchema
-A [RegionSchema](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/storage/src/schema/region.rs#L37) describes the schema of a region.
-
-```rust
-pub struct RegionSchema {
-    user_schema: SchemaRef,
-    store_schema: StoreSchemaRef,
-    columns: ColumnsMetadataRef,
-}
-```
-
-Each region reserves some columns called `internal columns` for internal usage:
-- `__sequence`, sequence number of a row
-- `__op_type`, operation type of a row, such as `PUT` or `DELETE`
-- `__version`, user-specified version of a row, reserved but not used. We might remove this in the future
-
-The table engine can't see the `__sequence` and `__op_type` columns, so the `RegionSchema` itself maintains two internal schemas:
-- User schema, a `Schema` struct that doesn't have internal columns
-- Store schema, a `StoreSchema` struct that has internal columns
-
-The `ColumnsMetadata` struct keeps metadata about all columns but most time we only need to use metadata in user schema and store schema, so we just ignore it. We may remove this struct in the future.
-
-`RegionSchema` organizes columns in the following order:
-```
-key columns, timestamp, [__version,] value columns, __sequence, __op_type
-```
-
-We can ignore the `__version` column because it is disabled now:
-
-```
-key columns, timestamp, value columns, __sequence, __op_type
-```
-
-Key columns are columns of a table's primary key. Timestamp is the time index column. A region sorts all rows by key columns, timestamp, sequence, and op type.
-
-So the `RegionSchema` of our `cpu` table above looks like this:
-```json
-{
-    "user_schema":[
-        "datacenter",
-        "host",
-        "ts",
-        "usage_user",
-        "usage_system"
-    ],
-    "store_schema":[
-        "datacenter",
-        "host",
-        "ts",
-        "usage_user",
-        "usage_system",
-        "__sequence",
-        "__op_type"
-    ]
-}
-```
-
-## StoreSchema
-As described above, a [StoreSchema](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/storage/src/schema/store.rs#L36) is a schema that knows all internal columns.
-```rust
-struct StoreSchema {
-    columns: Vec<ColumnMetadata>,
-    schema: SchemaRef,
-    row_key_end: usize,
-    user_column_end: usize,
-}
-```
-
-The columns in the `columns` and `schema` fields have the same order. The `ColumnMetadata` has metadata like column id, column family id, and comment. The `StoreSchema` also stores this metadata in `StoreSchema::schema`, so we can convert the `StoreSchema` between arrow's `Schema`. We use this feature to persist the `StoreSchema` in the SST since our SST format is `Parquet`, which can take arrow's `Schema` as its schema.
-
-The `StoreSchema` of the region above is similar to this:
-```json
-{
-    "schema":{
-        "column_schemas":[
-            "datacenter",
-            "host",
-            "ts",
-            "usage_user",
-            "usage_system",
-            "__sequence",
-            "__op_type"
-        ],
-        "time_index":2,
-        "version":0
-    },
-    "row_key_end":3,
-    "user_column_end":5
-}
-```
-
-The key and timestamp columns form row keys of rows. We put them together so we can use `row_key_end` to get indices of all row key columns. Similarly, we can use the `user_column_end` to get indices of all user columns (non-internal columns).
-```rust
-impl StoreSchema {
-    #[inline]
-    pub(crate) fn row_key_indices(&self) -> impl Iterator<Item = usize> {
-        0..self.row_key_end
-    }
-
-    #[inline]
-    pub(crate) fn value_indices(&self) -> impl Iterator<Item = usize> {
-        self.row_key_end..self.user_column_end
-    }
-}
-```
-
-Another useful feature of `StoreSchema` is that we ensure it always contains key columns, a timestamp column, and internal columns because we need them to perform merge, deduplication, and delete. Projection on `StoreSchema` only projects value columns.
-
-## ProjectedSchema
-To support arbitrary projection, we introduce the [ProjectedSchema](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/storage/src/schema/projected.rs#L106).
-```rust
-pub struct ProjectedSchema {
-    projection: Option<Projection>,
-    schema_to_read: StoreSchemaRef,
-    projected_user_schema: SchemaRef,
-}
-```
-
-We need to handle many cases while doing projection:
-- The columns' order of table and region is different
-- The projection can be in arbitrary order, e.g. `select usage_user, host from cpu` and `select host, usage_user from cpu` have different projection order
-- We support `ALTER TABLE` so data files may have different schemas.
-
-### Projection
-Let's take an example to see how projection works. Suppose we want to select `ts`, `usage_system` from the `cpu` table.
-
-```sql
-CREATE TABLE cpu (
-    ts TIMESTAMP,
-    host STRING,
-    usage_user DOUBLE,
-    usage_system DOUBLE,
-    datacenter STRING,
-    TIME INDEX (ts),
-    PRIMARY KEY(datacenter, host)) ENGINE=mito;
-
-select ts, usage_system from cpu;
-```
-
-The query engine uses the projection `[0, 3]` to scan the table. However, columns in the region have a different order, so the table engine adjusts the projection to `2, 4`.
-```json
-{
-    "user_schema":[
-        "datacenter",
-        "host",
-        "ts",
-        "usage_user",
-        "usage_system"
-    ],
-}
-```
-
-As you can see, the output order is still `[ts, usage_system]`. This is the schema users can see after projection so we call it `projected user schema`.
-
-But the storage engine also needs to read key columns, a timestamp column, and internal columns. So we maintain a `StoreSchema` after projection in the `ProjectedSchema`.
-
-The `Projection` struct is a helper struct to help compute the projected user schema and store schema.
-
-So we can construct the following `ProjectedSchema`:
-```json
-{
-    "schema_to_read":{
-        "schema":{
-            "column_schemas":[
-                "datacenter",
-                "host",
-                "ts",
-                "usage_system",
-                "__sequence",
-                "__op_type"
-            ],
-            "time_index":2,
-            "version":0
-        },
-        "row_key_end":3,
-        "user_column_end":4
-    },
-    "projected_user_schema":{
-        "column_schemas":[
-            "ts",
-            "usage_system"
-        ],
-        "time_index":0
-    }
-}
-```
-
-As you can see, `schema_to_read` doesn't contain the column `usage_user` that is not intended to be read (not in projection).
-
-### ReadAdapter
-As mentioned above, we can alter a table so the underlying files (SSTs) and memtables in the storage engine may have different schemas.
-
-To simplify the logic of `ProjectedSchema`, we handle the difference between schemas before projection (constructing the `ProjectedSchema`). We introduce [ReadAdapter](https://github.com/GreptimeTeam/greptimedb/blob/9fa871a3fad07f583dc1863a509414da393747f8/src/storage/src/schema/compat.rs#L90) that adapts rows with different source schemas to the same expected schema.
-
-So we can always use the current `RegionSchema` of the region to construct the `ProjectedSchema`, and then create a `ReadAdapter` for each memtable or SST.
-```rust
-#[derive(Debug)]
-pub struct ReadAdapter {
-    source_schema: StoreSchemaRef,
-    dest_schema: ProjectedSchemaRef,
-    indices_in_result: Vec<Option<usize>>,
-    is_source_needed: Vec<bool>,
-}
-```
-
-For each column required by `dest_schema`, `indices_in_result` stores the index of that column in the row read from the source memtable or SST. If the source row doesn't contain that column, the index is `None`.
-
-The field `is_source_needed` stores whether a column in the source memtable or SST is needed.
-
-Suppose we add a new column `usage_idle` to the table `cpu`.
-```sql
-ALTER TABLE cpu ADD COLUMN usage_idle DOUBLE;
-```
-
-The new `StoreSchema` becomes:
-```json
-{
-    "schema":{
-        "column_schemas":[
-            "datacenter",
-            "host",
-            "ts",
-            "usage_user",
-            "usage_system",
-            "usage_idle",
-            "__sequence",
-            "__op_type"
-        ],
-        "time_index":2,
-        "version":1
-    },
-    "row_key_end":3,
-    "user_column_end":6
-}
-```
-
-Note that we bump the version of the schema to 1.
-
-If we want to select `ts`, `usage_system`, and `usage_idle`. While reading from the old schema, the storage engine creates a `ReadAdapter` like this:
-```json
-{
-    "source_schema":{
-        "schema":{
-            "column_schemas":[
-                "datacenter",
-                "host",
-                "ts",
-                "usage_user",
-                "usage_system",
-                "__sequence",
-                "__op_type"
-            ],
-            "time_index":2,
-            "version":0
-        },
-        "row_key_end":3,
-        "user_column_end":5
-    },
-    "dest_schema":{
-        "schema_to_read":{
-            "schema":{
-                "column_schemas":[
-                    "datacenter",
-                    "host",
-                    "ts",
-                    "usage_system",
-                    "usage_idle",
-                    "__sequence",
-                    "__op_type"
-                ],
-                "time_index":2,
-                "version":1
-            },
-            "row_key_end":3,
-            "user_column_end":5
-        },
-        "projected_user_schema":{
-            "column_schemas":[
-                "ts",
-                "usage_system",
-                "usage_idle"
-            ],
-            "time_index":0
-        }
-    },
-    "indices_in_result":[
-        0,
-        1,
-        2,
-        3,
-        null,
-        4,
-        5
-    ],
-    "is_source_needed":[
-        true,
-        true,
-        true,
-        false,
-        true,
-        true,
-        true
-    ]
-}
-```
-
-We don't need to read `usage_user` so `is_source_needed[3]` is false. The old schema doesn't have column `usage_idle` so `indices_in_result[4]` is `null` and the `ReadAdapter` needs to insert a null column to the output row so the output schema still contains `usage_idle`.

 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 🤗
 
+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/nightly/user-guide/deployments/deploy-on-kubernetes/getting-started).
