-------------------------------------
Summary: Switch primary replica calls from Raft leader to primary
replica
Key: IGNITE-18856
URL: https://issues.apache.org/jira/browse/IGNITE-18856
Project: Ignite
Issue Type: Improvement
Reporter: Denis Chudov
Motivation
As for now, RW requests to primary replica (see calls of
`ReplicaService#invoke` ) are sent to raft leader, for which the refresh leader
operation is needed. In presence of placement driver which is responsible for
assigning primary replicas, this is not needed, the request can be sent
directly to primary replica node.
Th information about primary replicas assigned by placement driver should be
available on every node after ... . This task is about switching primary
replica calls and eliminating excessive code related to refreshing leader of
raft group.
Definition of done
Requests to primary replica are made to those nodes that are assigned by
placement driver, and no related Raft calls are made.
