Soumitra Kumar updated FLINK-39455:
-----------------------------------
Description:
RocksDB's associative merge operator is a powerful primitive, enabling
applications to express read-modify-write semantics (counters, sorted sets,
etc.) at the storage layer and defer the merge cost to flush and compaction
time.
There is no way to implement merge logic in pure Java without building and
distributing a native library. It would be great to support a pure Java-based
associative merge operator.
