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


Hi,

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 .

Best,
Stefan

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
