> Right now the new partial update support with partial updates stored in the log block works in Spark SQL MERGE INTO and the merging logic either based on the transaction time or event time is fully taken care inside "HoodieSparkRecordMerger".  It would be good to decouple the merging logic from the merger and use the record merge mode to control how to merge partial updates.
