Pavel Tupitsyn updated IGNITE-20701:
------------------------------------
Description:
h2. Problem
* *Partition Leader* and *Primary Partition Replica* can be two different
nodes.
* Primary replica can handle requests more efficiently
* *InternalTableImpl#assignments* is used for client partition awareness, but
it returns leaders
h2. Action Items
* Fix *ClientTablePartitionAssignmentGetRequest* to return primary replica per
partition
* Fix *ClientInboundMessageHandler.onPartitionAssignmentChanged* to notify
about primary change (lease based?)
* Fix *IgniteCompute.executeColocated* the same way
All the fixes are server-side; in theory, we don't need to fix the clients.
Consult [~sanpwc] for more details.
