[jira] [Created] (KAFKA-8784) Remove default implementation of RocksDBConfigSetter#close

Sophie Blee-Goldman created KAFKA-8784:
------------------------------------------

             Summary: Remove default implementation of RocksDBConfigSetter#close
                 Key: KAFKA-8784
                 URL: https://issues.apache.org/jira/browse/KAFKA-8784
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 3.0.0
            Reporter: Sophie Blee-Goldman


In 2.3 we added a new method to RocksDBConfigSetter that will be called when a store is closed to clean up any resources that may have been created in #setConfig. Many large objects such as the block cache might be instantiated in that method, which will leak memory if not closed since they are backed by C++ objects.

We should consider removing the default implementation to force users to pay attention to whether they may be leaking memory, even if it may be a no-op for many.
