------------------------------------------
Summary: Use state transition times for
SimpleConcurrentFileWritesConflictResolutionStrategy and other enhancements.
Key: HUDI-6353
URL: https://issues.apache.org/jira/browse/HUDI-6353
Project: Apache Hudi
Issue Type: Improvement
Reporter: Surya Prasanna Yalla
Couple of enhancements we can make to Multiwriter conflict resolution
strategies.
* Similar to how git rebase works, writers when creating a requested commit
should track the baseInstant on which they are executing, this will be the last
completed commit. Note, last completed commit can have commit timestamp less
than other completed commits in the timeline. Here, baseInstantTime is based on
the state transition times which is the last commit written to the timeline.
Conflict resolution strategies should happen based on this commit time.
* Similar to IngestionPrimaryWriterBasedConflictResolutionStrategy class, we
should use state transition times to find the conflicts. By using state
transition times the conflict resolution works similar to git rebase.
