Matthias J. Sax updated KAFKA-8324:
-----------------------------------
Description:
Some of the RocksDB options a user can set when extending RocksDBConfigSetter
take Rocks objects as parameters. Many of these – including potentially large
objects like Cache and Filter – inherit from AbstractNativeReference and must
be closed explicitly in order to free the memory of the backing C++ object.
However the user has no way of closing any objects they have created in
RocksDBConfigSetter, and we do not ever close them for them.
