[~Yanfei Lei] Thanks for your reply and yes, you are right. There is still a 
lot of works to do to support Ribbon filter policy.

Hi [~zlzhang0122],  {{rocksjni}} does not support [Ribbon filter 
policy|https://github.com/facebook/rocksdb/blob/main/java/rocksjni/filter.cc] 
yet, we should let rocks-jni support it first, and then pick the commits to 
frocksdb.
