Documentation: emseries - Rust

EmSeries is an Embedded Time Series database. It is designed for small-scale applications which need to track time series data, but on a scale that does not justify extra database services. I use it for Fitnesstrax, which keeps track of information recorded only a few times a day.

I intend to use it eventually for an application that receives data every few seconds from sensors scattered around my house.


  • Open a time series file directly in your application
  • Add, update, read, and delete records with arbitrary json-friendly structure
  • Search for records by timestamp and optional tags

Future Plans

  • Indexing based on time and tags
  • Support databases larger than memory
  • Multi-process safety

The actual extent of the features implemened will depend on how I and any others decide to use them.
