--------------------------------------
Summary: Add support for Java based AssociativeMergeOperator via
JNI
Key: FLINK-39455
URL: https://issues.apache.org/jira/browse/FLINK-39455
Project: Flink
Issue Type: Improvement
Reporter: Soumitra Kumar
RocksDB's associative merge operator is a powerful primitive, enabling
applications to express read-modify-write semantics (counters, sorted sets,
append logs, 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.
