Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * processWALSamples: update comment Previous text seems to relate to an earlier implementation. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Optimise WAL loading by removing extra map and caching min-time (#9160) * BenchmarkLoadWAL: close WAL after use So that goroutines are stopped and resources released Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * BenchmarkLoadWAL: make series IDs co-prime with #workers Series are distributed across workers by taking the modulus of the ID with the number of workers, so multiples of 100 are a poor choice. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * BenchmarkLoadWAL: simulate mmapped chunks Real Prometheus cuts chunks every 120 samples, then skips those samples when re-reading the WAL. Simulate this by creating a single mapped chunk for each series, since the max time is all the reader looks at. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Fix comment Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Remove series map from processWALSamples() The locks that is commented to reduce contention in are now sharded 32,000 ways, so won't be contended. Removing the map saves memory and goes just as fast. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * loadWAL: Cache the last mmapped chunk time So we can skip calling append() for samples it will reject. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Improvements from code review Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Full stops and capitals on comments Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Cache max time in both places mmappedChunks is updated Including refactor to extract function `setMMappedChunks`, to reduce code duplication. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Update head min/max time when mmapped chunks added This ensures we have the correct values if no WAL samples are added for that series. Note that `mSeries.maxTime()` was always `math.MinInt64` before, since that function doesn't consider mmapped chunks.
