Yun Tang commented on FLINK-28010:
----------------------------------
[~Ming Li] Since we do not have a special separator between the primary key and
user key, we need to use the next byte array to represent the prefix bytes. If
so, I think we can make this.
> Use deleteRange to optimize the clear operation of RocksDBMapState.
