------------------------------------
Summary: Extract simple and direct RO handlers from
PartitionReplicaListener if-else chain
Key: IGNITE-28333
URL: https://issues.apache.org/jira/browse/IGNITE-28333
Project: Ignite
Issue Type: Improvement
Components: replicated zones ai3
Reporter: Ivan Zlenko
Assignee: Ivan Zlenko
This is the next increment of the
PartitionReplicaListener.processOperationRequest refactoring
([IGNITE-28293|https://issues.apache.org/jira/browse/IGNITE-28293]).
The first increment introduced the handler registry pattern
(ReplicaRequestHandlers) and extracted 2 handlers
(BuildIndexReplicaRequestHandler, ScanCloseRequestHandler). This increment
extracts 4 more handlers that fit cleanly into the existing interfaces.
Simple handlers (use ReplicaRequestHandler, no extra context needed):
TableWriteIntentSwitchReplicaRequest → extract from
processTableWriteIntentSwitchAction
TxStatePrimaryReplicaRequest → extract from
processTxStatePrimaryReplicaRequest
Direct RO handlers (use ReadOnlyReplicaRequestHandler):
ReadOnlyDirectSingleRowReplicaRequest → extract from
processReadOnlyDirectSingleEntryAction
ReadOnlyDirectMultiRowReplicaRequest → extract from
processReadOnlyDirectMultiEntryAction
After this, 9 handlers will remain in the if-else chain (6 RW + 3 RO
non-direct), which requires additional context (leaseStartTime, isPrimary)
passed through to the handler.
