jihoonson opened a new pull request #8161: Add benchmark for VersionedIntervalTimeline URL: https://github.com/apache/incubator-druid/pull/8161 Benchmark for VersionedIntervalTimeline introduced in https://github.com/apache/incubator-druid/pull/7547#issuecomment-511966275. ## Description The primary purpose of this benchmark is to measure how much slower VersionedIntervalTimeline is with segment lock than with timeChunk lock. ### Data setup A synthetic segments were created to emulate the usual compaction scenario where initial segments are created and then they got compacted while new segments are appended. The benchmark first generates `numInitialRootGenSegmentsPerInterval` segments per interval. Then, it generates `numInitialRootGenSegmentsPerInterval * COMPACTED_SEGMENTS_RATIO_TO_INITIAL_SEGMENTS` compacted segments which overwrites the segments of the previous generation. It also generates new appending segments. This can be repeated more than once based on `numNonRootGenerations`. <hr> This PR has: - [x] been self-reviewed.
