> Key: KAFKA-8784
> URL: https://issues.apache.org/jira/browse/KAFKA-8784
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Sophie Blee-Goldman
> Priority: Blocker
> Fix For: 3.0.0

>
> 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.
