[~Aminouvic] I will close this issue for now because of inactivity and lack of 
further evidence that there is a problem.

The test you mentioned is part of the flink test suite, specifically it became 
{{RocksDBPerformanceTest#testRocksDbMergePerformance}}. This test is passing 
and there is no sign of performance regression in my opinion.
