Vladislav Pyatkov updated IGNITE-19136:
---------------------------------------
Description:
*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 this case is not complied for read only requests. The result is unhandled
exception:
{noformat}
Replica is not ready

*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.
