## What is GreptimeDB ## Introduction
GreptimeDB is an open-source time-series database focusing on efficiency, scalability, and analytical capabilities. **GreptimeDB** is an open-source time-series database focusing on efficiency, scalability, and analytical capabilities.
It's designed to work on infrastructure of the cloud era, and users benefit from its elasticity and commodity storage. 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**.
Our core developers have been building time-series data platforms for years. Based on their best-practices, GreptimeDB is born to give you: ## Why GreptimeDB
* **Compatible with InfluxDB, Prometheus and more protocols**: Widely adopted database protocols and APIs, including MySQL, PostgreSQL, and Prometheus Remote Storage, etc. [Read more](https://docs.greptime.com/user-guide/clients/overview). Our core developers have been building time-series data platforms for years. Based on our best-practices, GreptimeDB is born to give you:
* **Easy horizontal scaling**: 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.
* **Analyzing time-series data**: Native SQL and PromQL for queries, and Python scripting to facilitate complex analytical tasks.
* **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.
