Andrey Zagrebin updated FLINK-9514:
-----------------------------------
Description:
TTL state decorator uses original state with packed TTL and add TTL logic using
time provider:
{code:java}
TtlValueState<V> implements ValueState<V> {
ValueState<TtlValue<V>> underlyingState;
InternalTimeService timeProvider;
V value() {
TtlValue<V> valueWithTtl = underlyingState.get();
// ttl logic here (e.g. update timestamp)
return valueWithTtl.getValue();
}
void update() { ... underlyingState.update(valueWithTtl) ... }
}
{code}
TTL decorators are apply to state produced by normal state binder in its TTL
wrapper from FLINK-9513
