Vladislav Pyatkov updated IGNITE-19136:
---------------------------------------
Summary: Handling timeout on waiting for replica readiness (was: Handling
timeout on waiting for replica rediness)
> Handling timeout on waiting for replica readiness
> -------------------------------------------------
>
> Key: IGNITE-19136
> URL: https://issues.apache.org/jira/browse/IGNITE-19136
> Project: Ignite
> Issue Type: Bug
> Reporter: Vladislav Pyatkov
> Priority: Major
> Labels: ignite-3
>
> *Motivation*
> There are several reasons by the replica can respond
> _ReplicaNotReadyException_ (storage recovery has not completed yet, indexes
> have not created). In this case, required sending AwaitReplicaRequest and
> don't try requesting any more until AwaitReplicaResponse doesn't be received.
> But the reason is not obvious when we receive a timeout on waiting for the
> replica readiness. The result is an unhandled exception:
> {noformat}
> Replica is not ready
> [replicationGroupId=474283c9-a39e-431a-895f-751003052d7a_part_10,
> nodeName=irott_n_1]

> at [email protected]/java.lang.Thread.run(Thread.java:834)
> {noformat}
> *Workaround*
> Currently, when we use RW transaction before to use RO transaction, the issue
> won't be reproduced. Because RW transaction is waiting for the replica
> becomes ready.
> *Definition of Done*
> All types of request (RW, RO) should handle _ReplicaNotReadyException_ and
> wait for the replica will be ready to handle them.
