Re: are there any ways to test the performance of rocksdb state backend?


Sihua is right, of course we would like to update our RocksDB version but are currently blocked on a performance regression. Here is our issue in the RocksDB tracker for this: https://github.com/facebook/rocksdb/issues/3865 .

Hi makeyang,
there are some cases under _org.apache.flink.contrib.streaming.state.benchmark.*_ that you can refer to. But, I not sure whether it's possible to upgrade the RocksDB to any higher version because the regression of the merge operator, the comments in this PR https://github.com/apache/flink/pull/5937 may also give you some help.

Best, Sihua
