About the project

Jaeger-tsdb is a Jaeger storage plugin based on the grpc-plugin mechanism. It stores Jaeger's data using Promemtheus TSDB (actually modified version).

This project is for fun and practise. Please don't use it in production :). Because the high cardinality data model is not suitable for Prometheus TSDB.

The storage also cannot support span duration query because the limitation of the Prometheus TSDB.
