 ## 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 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 |
-| --------- | ----------- |
-| [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 is 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
+* **Easy horizontal scaling**
 
-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).
+  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.
 
-## Quick Comparison
+* **Analyzing time-series data**
 
-| Feature                         | GreptimeDB            | Traditional TSDB   | Log Stores      |
-|----------------------------------|-----------------------|--------------------|-----------------|
-| Data Types                      | Metrics, Logs, Traces | Metrics only       | Logs only       |
-| Query Language                  | SQL, PromQL |  Custom/PromQL     | Custom/DSL      |
-| Deployment                      | Edge + Cloud          | Cloud/On-prem      | Mostly central  |
-| Indexing & Performance          | PB-Scale, Sub-second  | Varies             | Varies          |
-| Integration                     | REST API, SQL, Common protocols | Varies     | Varies          |
+  Query your time-series data with SQL and PromQL. Use Python scripts to facilitate complex analytical tasks.
 
-**Performance:**
-* [GreptimeDB tops JSONBench's billion-record cold run test!](https://greptime.com/blogs/2025-03-18-jsonbench-greptimedb-performance)
-* [TSBS Benchmark](https://github.com/GreptimeTeam/greptimedb/tree/main/docs/benchmarks/tsbs)
+* **Cloud-native distributed database**
 
-Read [more benchmark reports](https://docs.greptime.com/user-guide/concepts/features-that-you-concern#how-is-greptimedbs-performance-compared-to-other-solutions).
+  Fully open-source distributed cluster architecture that harnesses the power of cloud-native elastic computing resources.
 
-## Architecture
+* **Performance and Cost-effective**
 
-GreptimeDB can run in two modes:
-* **Standalone Mode** - Single binary for development and small deployments
-* **Distributed Mode** - Separate components for production scale:
-  - Frontend: Query processing and protocol handling
-  - Datanode: Data storage and retrieval
-  - Metasrv: Metadata management and coordination
+  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.

+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-administration/configuration#storage-options).
