Piotr Nowojski commented on FLINK-15104:
----------------------------------------
I'm pretty sure the performance regression is real. As you can see those
benchmarks are pretty stable (especially non incremental one).
It might be small, however the problem is that the benchmark coverage for real
world usage of RocksDB is very small. It could well be that this change is
affecting other use cases in much more profound way, so I wouldn't ignore it
without first trying to understand what has happened/changed.

> Issue Type: Bug
> Components: Benchmarks, Runtime / State Backends
> Reporter: Piotr Nowojski

>
> A potential small performance regression that happened either on December 4th
> or 5th:
> http://codespeed.dak8s.net:8000/timeline/?ben=stateBackends.ROCKS&env=2
> http://codespeed.dak8s.net:8000/timeline/?ben=stateBackends.ROCKS_INC&env=2
> it doesn't seem to be visible in the states benchmarks suites, which might be
> an issue on its own.
