 ## Introduction
 
-**GreptimeDB** is an open-source, cloud-native database purpose-built for the unified collection and analysis of observability data (metrics, logs, and traces). Whether you’re operating on the edge, in the cloud, or across hybrid environments, GreptimeDB empowers real-time insights at massive scale — all in one system.
+**GreptimeDB** is an open-source time-series database focusing on efficiency, scalability, and analytical capabilities.
+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**.
 
-## Features
+## Why GreptimeDB
 
-|   Feature  | Description |
-| --------- | ----------- |
-| [Unified Observability Data](https://docs.greptime.com/user-guide/concepts/why-greptimedb) | Store metrics, logs, and traces as timestamped, contextual wide events. Query via [SQL](https://docs.greptime.com/user-guide/query-data/sql), [PromQL](https://docs.greptime.com/user-guide/query-data/promql), and [streaming](https://docs.greptime.com/user-guide/flow-computation/overview). |
-| [High Performance & Cost Effective](https://docs.greptime.com/user-guide/manage-data/data-index) | Written in Rust, with a distributed query engine, [rich indexing](https://docs.greptime.com/user-guide/manage-data/data-index), and optimized columnar storage, delivering sub-second responses at PB scale. |
-| [Cloud-Native Architecture](https://docs.greptime.com/user-guide/concepts/architecture) | Designed for [Kubernetes](https://docs.greptime.com/user-guide/deployments-administration/deploy-on-kubernetes/greptimedb-operator-management), with compute/storage separation, native object storage (AWS S3, Azure Blob, etc.) and seamless cross-cloud access. |
-| [Developer-Friendly](https://docs.greptime.com/user-guide/protocols/overview) | Access via SQL/PromQL interfaces, REST API, MySQL/PostgreSQL protocols, and popular ingestion [protocols](https://docs.greptime.com/user-guide/protocols/overview). |
-| [Flexible Deployment](https://docs.greptime.com/user-guide/deployments-administration/overview) | Deploy anywhere: edge (including ARM/[Android](https://docs.greptime.com/user-guide/deployments-administration/run-on-android)) or 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 is born to give you:
 
-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).
+* **Easy horizontal scaling**
 
-## Quick Comparison

+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.

-# There's also another solution to this, that we add the desired submodules to the safe directory, instead of using 
-# wildcard here. However, that requires the git's config files and the submodules all owned by the very same user.
-# It's troublesome to do this since the dev build runs in Docker, which is under user "root"; while outside the Docker,
-# it can be a different user that have prepared the submodules.

-# 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-administration/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`.

-## 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 \

-Rerun queries need not to re-import data. Just execute the corresponding command again is fine.

-# Change Log Level on the Fly
-
-## HTTP API
-
-example:
-```bash
-curl --data "trace,flow=debug" 127.0.0.1:4000/debug/log_level
-```
-And database will reply with something like:
-```bash
-Log Level changed from Some("info") to "trace,flow=debug"%
-```
-
-The data is a string in the format of `global_level,module1=level1,module2=level2,...` that follows the same rule of `RUST_LOG`. 
-
-The module is the module name of the log, and the level is the log level. The log level can be one of the following: `trace`, `debug`, `info`, `warn`, `error`, `off`(case insensitive).
