------------------------------------------
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.
