case class TTLConfig(ttlDuration: Duration) extends Product with Serializable
TTL Configuration for state variable. State values will not be returned past ttlDuration, and will be eventually removed from the state store. Any state update resets the ttl to current processing time plus ttlDuration.
Passing a TTL duration of zero will disable the TTL for the state variable. Users can also use
the helper method TTLConfig.NONE in Scala or TTLConfig.NONE() in Java to disable TTL for
the state variable.
- ttlDuration
time to live duration for state stored in the state variable.
