sanastas commented on issue #5698: Oak: New Concurrent Key-Value Map URL: https://github.com/apache/incubator-druid/issues/5698#issuecomment-506257347 @jihoonson , sounds good! > One benchmark is for directly comparing performance of OakIncrementalIndex and OnheapIncrementalIndex (and optionally OffheapIncrementalIndex to show how optimized OakIncrementalIndex is to store data in off-heap memory). We have found OffheapIncrementalIndex not-optimized in some places, not so concurrent (synchronize on everything) and it looks like it not in use. Thus we decided not to compare to it as even in the tests/benchmarks there are some exceptions happening with OffheapIncrementalIndex.... > The benchmark result would include both ingestion throughput and latency to see how GC could affect to the ingestion performance. Is it something like two graphs under "IncrementalIngestionBenchmark results" presented above? Is it the latency that you are missing? Or different parameters?
