Revision e80dd00894128e0bcc0ba6143fca9a35e7b4279e authored by mmsqe on 13 September 2022, 08:42:14 UTC, committed by GitHub on 13 September 2022, 08:42:14 UTC
* Performance improvements for the event query API (#7319) Rework the implementation of event query parsing and execution to improve performance and reduce memory usage. Previous memory and CPU profiles of the pubsub service showed query processing as a significant hotspot. While we don't have evidence that this is visibly hurting users, fixing it is fairly easy and self-contained. Updates #6439. Typical benchmark results comparing the original implementation (PEG) with the reworked implementation (Custom): ``` TEST TIME/OP BYTES/OP ALLOCS/OP SPEEDUP MEM SAVING BenchmarkParsePEG-12 51716 ns 526832 27 BenchmarkParseCustom-12 2167 ns 4616 17 23.8x 99.1% BenchmarkMatchPEG-12 3086 ns 1097 22 BenchmarkMatchCustom-12 294.2 ns 64 3 10.5x 94.1% ```
