Andrey Zagrebin updated FLINK-9511:
-----------------------------------
Description:
`TtlConfig` has to be in flink core module.
Another option is to consider adding TtlConfig builder.
was:
TTL can be enabled and configured in the constructor of abstract
StateDescriptor and become available in all subclasses:
| {code:java}
enum StateTtlUpdateType { Disabled, OnCreateAndWrite, OnReadAndWrite }
enum StateTtlCleanupGuarantee { Relaxed, Exact }
enum TtlStateVisibility { Relaxed, Exact }
class TtlConfig {
StateTtlUpdateType updateType;
StateTtlCleanupGuarantee cleanupStrategy;
TtlStateVisibility stateVisibility;
TimeCharacteristic timeCharacteristic;
long ttl;
}
// previous constructor
StateDescriptor(...) {
this.ttlConfig = ttlConfig.DISABLED;
}
// overloaded constructor with TtlConfig
StateDescriptor(..., ttlConfig) {
...
}
{code}
