Bryan Boreham 60804c5a09 remote_write: reduce blocking from garbage-collect of series (#9109 ) * Refactor: pass segment-reading function as param To allow a different implementation to be used when garbage-collecting. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * remote_write: reduce blocking from GC of series Add a method `UpdateSeriesSegment()` which is used together with `SeriesReset()` to garbage-collect old series. This allows us to split the lock around queueManager series data and avoid blocking `Append()` while reading series from the last checkpoint. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Cosmetic: review feedback on comments Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * remote-write benchmark: include GC of series Reduce the total number of samples per iteration from 50005000 (25 million) which is too big for my laptop, to 110000. Extend `createTimeseries()` to add additional labels, so that the queue manager is doing more realistic work. Move the Append() call to a background goroutine - this works because TestWriteClient uses a WaitGroup to signal completion. Call `StoreSeries()` and `SeriesReset()` while adding samples, to simulate the garbage-collection that wal.Watcher does. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Change BenchmarkSampleDelivery to call UpdateSeriesSegment This matches what Watcher.garbageCollectSeries() is doing now Signed-off-by: Bryan Boreham <bjboreham@gmail.com>		3 years ago
