title: Kafka Streams: Dynamically Configure RocksDb
body: <p>I want to tune performance of Kafka Streams, and for that I have to play with RocksDb configuration values. </p>
  
  <p>I see I can use the <code>StreamsConfig.ROCKSDB_CONFIG_SETTER_CLASS_CONFIG</code> to set the configuration for RocksDB. Like shown <a href="https://kafka.apache.org/10/documentation/streams/developer-guide/config-streams.html" rel="nofollow noreferrer">here</a>.</p>
  
  <p>But I would like a way to configure it dynamically from configuration (in order to change the thresholds without having to compile and deploy all my code.</p>
  
  <p>Is there an option to somehow give concrete implementation instance instead of a class name? (This will allow to set the thresholds, for example, using a properties file)</p>
