GreptimeDB
GreptimeDB: the next-generation hybrid timeseries/analytics processing database in the cloud.
Getting Started
Prerequisites
To compile GreptimeDB from source, you'll need the following:
- Rust
- C++ toolchain
- cmake
- OpenSSL
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.
C++ toolchain
The prost-build dependency requires C++ toolchain and cmake to build its bundled protoc. For more info on what the required dependencies are check here.
cmake
Follow the instructions for your operating system on the cmake site.
For macOS users, you can also use homebrew to install cmake.
brew install cmake
OpenSSL
For Ubuntu:
sudo apt install libssl-dev
For RedHat-based: Fedora, Oracle Linux, etc:
sudo dnf install openssl-devel
For macOS:
brew install openssl
Usage
// Start datanode with default options.
cargo run -- datanode start
OR
// Start datanode with `http-addr` option.
cargo run -- datanode start --http-addr=0.0.0.0:9999
OR
// Start datanode with `log-dir` and `log-level` options.
cargo run -- --log-dir=logs --log-level=debug datanode start
