Peidian Li updated FLINK-17302:
-------------------------------
Description:
Users that need to lookup many keys in order to process an application level
request end up calling Get() in a loop to read the required KVs. Rocksdb
provides multiget() interface to improve reading efficiency.Do we consider
providing multiget() interface for rocksdb statebackend ？
See also [https://github.com/facebook/rocksdb/wiki/MultiGet-Performance].
For other statebackend, we can call the get () interface in a loop to
implement multiget().
