rusty-chunkenc
A Rust implementation of Prometheus' chunkenc library.
Features
- Parse Prometheus XOR-encoded chunks (that are heavily inspired by Gorilla).
- Serialise time series to Prometheus XOR-encoded chunks.
- Read Prometheus' cold data directly from the disk.
- Also comes with utilities to read and write
varint,uvarint,varbit,varbit_ts, andvarbit_xornumbers.
Why?
Prometheus uses XOR Chunks in its remote read API, and I wanted to understand how they work in detail. This crate enables SensApp to stream data to Prometheus. SensApp is written in Rust, and I wanted a chunkenc Rust implementation.
Also, writing a parser and a serialiser did sound fun.

Acknowledgements
This project is ported from Prometheus' chunkenc, that used go-tzs, that is based on the Gorilla paper. The parsing heavily relies on nom.
The project supports the Smart Building Hub research infrastructure project, which is funded by the Norwegian Research Council.
