What is GreptimeDB

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.

Our core developers have been building time-series data platforms for years. Based on their best-practices, GreptimeDB is born to give you:

  • Optimized columnar layout for handling time-series data; compacted, compressed, and stored on various storage backends, particularly cloud object storage with 50x cost efficiency.
  • Fully open-source distributed cluster architecture that harnesses the power of cloud-native elastic computing resources.
  • 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.
  • Native SQL and PromQL for queries, and Python scripting to facilitate complex analytical tasks.
  • Flexible indexing capabilities and distributed, parallel-processing query engine, tackling high cardinality issues down.
  • Widely adopted database protocols and APIs, including MySQL, PostgreSQL, and Prometheus Remote Storage, etc.

Build

Build from Source

To compile GreptimeDB from source, you'll need:

  • C/C++ Toolchain: provides basic tools for compiling and linking. This is available as build-essential on ubuntu and similar name on other platforms.
  • Rust: the easiest way to install Rust is to use rustup, which will check our rust-toolchain file and install correct Rust version for you.
  • Protobuf: protoc is required for compiling .proto files. protobuf is available from major package manager on macos and linux distributions. You can find an installation instructions here. Note that protoc version needs to be >= 3.15 because we have used the optional keyword. You can check it with protoc --version.
  • python3-dev or python3-devel(Optional feature, only needed if you want to run scripts in CPython, and also need to enable pyo3_backend feature when compiling(by cargo run -F pyo3_backend or add pyo3_backend to src/script/Cargo.toml 's features.default like default = ["python", "pyo3_backend])): this install a Python shared library required for running Python scripting engine(In CPython Mode). This is available as python3-dev on ubuntu, you can install it with sudo apt install python3-dev, or python3-devel on RPM based distributions (e.g. Fedora, Red Hat, SuSE). Mac's Python3 package should have this shared library by default. More detail for compiling with PyO3 can be found in PyO3's documentation.

Build with Docker

A docker image with necessary dependencies is provided:

docker build --network host -f docker/Dockerfile -t greptimedb .

Run

Start GreptimeDB from source code, in standalone mode:

cargo run -- standalone start

Or if you built from docker:

docker run -p 4002:4002 -v "$(pwd):/tmp/greptimedb" greptime/greptimedb standalone start

Please see the online document site for more installation options and operations info.

Get started

Read the complete getting started guide on our official document site.

To write and query data, GreptimeDB is compatible with multiple protocols and clients.

Resources

Installation

  • Pre-built Binaries: For Linux and macOS, you can easily download pre-built binaries including official releases and nightly builds that are ready to use. In most cases, downloading the version without PyO3 is sufficient. However, if you plan to run scripts in CPython (and use Python packages like NumPy and Pandas), you will need to download the version with PyO3 and install a Python with the same version as the Python in the PyO3 version. We recommend using virtualenv for the installation process to manage multiple Python versions.
  • Docker Images(recommended): pre-built Docker images, this is the easiest way to try GreptimeDB. By default it runs CPython script with pyo3_backend enabled.
  • gtctl: the command-line tool for Kubernetes deployment

Project Status

This project is in its early stage and under heavy development. We move fast and break things. Benchmark on development branch may not represent its potential performance. We release pre-built binaries constantly for functional evaluation. Do not use it in production at the moment.

For future plans, check out GreptimeDB roadmap.
