What changes were proposed in this pull request?

Remove intermittent testRocksDBKeyMayExistApi, which was an "integration" test checking if RocksDB keyMayExist call is cheaper than get call for the same key.

There are several problems with it:

  • No warmup, so order matters. (Adding warmup reduces time of both calls.)
  • Same key names are used for both get and keyMayExist calls, the result of get might be cached at RocksDB level. (This should help keyMayExist due to current order. Reordering the loops indicates that keyMayExist takes longer than get.)
  • Too few measurements, no check of whether the difference is statistically significant.
  • Tests a completely empty database (does not match real life usage)
  • Measured time includes getBytesUtf16 calls, not only the RocksDB call being tested.

A real JMH-based microbenchmark would be better for that purpose.

Makes sense to remove, doesn't look like a unit test itself to me, seems like a performance test....
