Y Ethan Guo updated HUDI-8575:
------------------------------
Priority: Blocker (was: Major)
> Revisit payload class hierarchy
> -------------------------------
>
> Key: HUDI-8575
> URL: https://issues.apache.org/jira/browse/HUDI-8575
> Project: Apache Hudi
> Issue Type: Improvement
> Reporter: Y Ethan Guo
> Priority: Blocker
> Fix For: 1.1.0
>
>
> From the legacy, OverwriteWithLatestAvroPayload is used for event-time
> ordering implemented in the #preCombine, which is used by the merged log
> scanner in MOR table (note that this support is limited since
> OverwriteWithLatestAvroPayload#combineAndGetUpdateValue still ignores
> ordering value), until DefaultHoodieRecordPayload is added to support
> event-time ordering. However, `OverwriteWithLatestAvroPayload` is supposed
> to follow the commit-time ordering, and HUDI-8521 fixes that in Hudi 1.0.
> During the changes, we see that many payload implementations like
> AbstractDebeziumAvroPayload which has event time semantics still extend
> OverwriteWithLatestAvroPayload. To maintain the same behavior as before,
> HUDI-8521 makes each of such payload classes to override the preCombine logic.
> We should revisit the payload class hierarchy so that such payload class may
> extend
> DefaultHoodieRecordPayload.
