------------------------------------
Summary: RocksDB objects needs to be disposed after usage
Key: KAFKA-3735
URL: https://issues.apache.org/jira/browse/KAFKA-3735
Project: Kafka
Issue Type: Bug
Components: streams
Reporter: Guozhang Wang
Assignee: Guozhang Wang
The RocksDB JNI interface {{RocksObject}} has a dispose() function which need
to be explicitly triggered after it is not reused, otherwise GC may not be able
to de-reference it off-heap and hence effective lead to memory leak. See:
https://github.com/facebook/rocksdb/issues/752#issuecomment-146511412
We need to make sure all library-controlled RocksDB objects are disposed after
usage, and also indicate users to {{close}} those out-of-control objects.
