title: Kafka Streams - Low-Level Processor API - RocksDB TimeToLive(TTL)
body: <p>I'm kind of experimenting with the low level processor API. I'm doing data aggregation on incoming records using the processor API and writing the aggregated records to RocksDB. </p>
  
  <p>However, I want to retain the records added in the rocksdb to be active only for 24hr period. After 24hr period the record should be deleted.  This can be done by changing the ttl settings. However, there is not much documentation where I can get some help on this. </p>
  
  <p>how do I change the ttl value? What java api should I  use to set the ttl time to 24 hrs and whats the current default ttl settings time?</p>
