Bartlomiej Plotka a73202012b tsdb/wlog[PERF]: optimize WAL watcher reads (up to 540x less B/op; 13000x less allocs/op) (#18250) ... See the detailed analysis https://docs.google.com/document/d/1efVAMcEw7-R_KatHHcobcFBlNsre-DoThVHI8AO2SDQ/edit?tab=t.0 I ran extensive benchmarks using synthetic data as well as real WAL segments pulled from the prombench runs. All benchmarks are here https://github.com/prometheus/prometheus/compare/bwplotka/wal-reuse?expand=1 * optimization(tsdb/wlog): reuse Ref* buffers across WAL watchers' reads Signed-off-by: bwplotka <bwplotka@gmail.com> * optimization(tsdb/wlog): avoid expensive error wraps Signed-off-by: bwplotka <bwplotka@gmail.com> * optimization(tsdb/wlog): reuse array for filtering Signed-off-by: bwplotka <bwplotka@gmail.com> * fmt Signed-off-by: bwplotka <bwplotka@gmail.com> * lint fix Signed-off-by: bwplotka <bwplotka@gmail.com> * tsdb/record: add test for clear() on histograms Signed-off-by: bwplotka <bwplotka@gmail.com> * updated WriteTo with what's currently expected Signed-off-by: bwplotka <bwplotka@gmail.com> --------- Signed-off-by: bwplotka <bwplotka@gmail.com>		18 hours ago
