- All Implemented Interfaces:
public class IndeterminateOperationStateException extends HazelcastException
For instance, an invocation doesn't receive enough ACKs from the backup replicas in time.
In this case, IndeterminateOperationStateException only informs the caller that the operation may not be executed
on all requested backup replicas, hence durability of the written / updated value may not be guaranteed immediately.
This timeout is defined by configuration property
Similarly, if the member, which owns the primary replica of the operation's target partition, leaves the cluster before a response is returned, then
operation is not retried but fails with IndeterminateOperationStateException. However, there will not be any rollback on other successful replicas.
Last, if a Raft group leader leaves the cluster before sending a response for the invocation, the invocation may terminate without knowing if the operation is committed or not.
