             Summary: File descriptor leaking (Too many open files) for long running stream process
                 Key: KAFKA-3904
                 URL: https://issues.apache.org/jira/browse/KAFKA-3904
             Project: Kafka
          Issue Type: Bug
          Components: streams
            Reporter: Henry Cai
            Assignee: Henry Cai


Today most of the rocksDB configs are hard written inside {{RocksDBStore}}, or the default values are directly used. We need to make them configurable for advanced users. For example, some default values may not work perfectly for some scenarios: https://github.com/HenryCaiHaiying/kafka/commit/ccc4e25b110cd33eea47b40a2f6bf17ba0924576 

One way of doing that is to introduce a "RocksDBStoreConfigs" objects similar to "StreamsConfig", which defines all related rocksDB options configs, that can be passed as key-value pairs to "StreamsConfig".
