* Fix panic on WAL replay Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Refactor: introduce walSubsetProcessor walSubsetProcessor packages up the `processWALSamples()` function and its input and output channels, helping to clarify how these things relate. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Refactor: extract more methods onto walSubsetProcessor This makes the main logic easier to follow. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Fix race warning by locking processWALSamples Although we have waited for the processor to finish, we still get a warning from the race detector because it doesn't know how the different parts relate. Add a lock round each batch of samples, so the race detector can see that we never access series owned by the processor outside of a lock. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Added test to reproduce issue 9859 Signed-off-by: Marco Pracucci <marco@pracucci.com> * Remove redundant unit test Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Fix out of order chunks during WAL replay Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Fix nits Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> Co-authored-by: Ganesh Vernekar <ganeshvern@gmail.com> Co-authored-by: Marco Pracucci <marco@pracucci.com> |

TSDB
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Due to an issue with versioning, the "latest" docs shown on Godoc are outdated.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
