Hi, Avi Levi
I don't think there's any way to solve this problem right now, and Flink documentation clearly shows that this is not supported.
“Trying to restore state, which was previously configured without TTL, using TTL enabled descriptor or vice versa will lead to compatibility failure and StateMigrationException
."

Hi,
I added a ttl to my state
old version :
private lazy val stateDescriptor = new ValueStateDescriptor("foo", Types.CASE_CLASS[DomainState])
vs the new version
@transient
private lazy val storeTtl = StateTtlConfig.newBuilder(90)
.setUpdateType(StateTtlConfig.UpdateType.OnCreateAndWrite)
.setStateVisibility(StateTtlConfig.StateVisibility.NeverReturnExpired)
.cleanupInRocksdbCompactFilter()
.build()
private lazy val stateDescriptor = {
val des = new ValueStateDescriptor("foo", Types.CASE_CLASS[DomainState])
des.enableTimeToLive(storeTtl)
des
}
BUT when trying to restore from savepoint I am getting this error:

Do you have any idea how can I resolve it ?
