Ethan Guo commented on HUDI-7847:
---------------------------------
Note that HUDI-6798 has added the inference logic on the new record merge mode
table config in HoodieTableMetaClient#inferRecordMergeMode (see
[https://github.com/apache/hudi/pull/9894).] We can reuse the same logic
during table upgrade from table version 7 to 8 (SevenToEightUpgradeHandler).

> Record merge mode is required to dictate the merging behavior in release 1.x,
> playing the same role as the payload class config in the release 0.x. During
> table upgrade, we need to infer the record merge mode based on the payload
> class so it's correctly set.
