-------------------------------------------
Summary: CPCC. Handling primary replica change
Key: IGNITE-24470
URL: https://issues.apache.org/jira/browse/IGNITE-24470
Project: Ignite
Issue Type: Task
Components: sql
Affects Versions: 3.0
Reporter: Evgeny Stanilovsky
Nodes observes meta-store globalOperationStatus#STARTED and start to fill node
related information - CpccOperation#operations
Nodes self update meta-store status records according to planned resizing jobs.
Need to correctly handle primary replica change, it can be three variants here:
# CPCC is just started, globalOperationStatus in (INITIATED or STARTED) states
and no node is assigned primary changed partition - further cpcc related flow
can be continued.
# CPCC in progress and primary replica change affects already processing
partitions - cpcc need to fail (with further zone unlock and garbage clean)
with appropriate return code and CpccOperation#failureReason
# CPCC in progress but primary replica change happens after partition already
replicated into newly created group - further cpcc related flow can be
continued.
Definition of done: upper cases need to be covered by tests, related
functionality implemented.
