Hi Vasily After Flink-1.10, state will be cleaned up periodically as CleanupInBackground is enabled by default. Thus, even you never access some specific entry of state and that entry could still be cleaned up.

I'm a bit confused with this point in State TTL documentation: " By default, expired values are explicitly removed on read, such as ValueState#value, and periodically garbage collected in the background if supported by the configured state backend. " Does it mean, that if i have only one event with specific key, it's state will never be cleaned on TTL expiration cause of i will never call value method for this key again?
