* tsdb/agent: port grafana/agent#676 grafana/agent#676 fixed an issue where a loading a WAL with multiple segments may result in ref ID collision. The starting ref ID for new series should be set to the highest ref ID across all series records from all WAL segments. This fixes an issue where the starting ref ID was incorrectly set to the highest ref ID found in the newest segment, which may not have any ref IDs at all if no series records have been appended to it yet.

This directory contains the Prometheus TSDB (Time Series DataBase) library, which handles storage and querying of all Prometheus v2 data.
Due to an issue with versioning, the "latest" docs shown on Godoc are outdated. Instead you may use the docs for v2.31.1
