Review Comment:
I don't think so. In HoodieAvroRecordMerger, we do
`combineAndGetUpdateValue` before writing and shuffling is done before
`combineAndGetUpdateValue`. We do `preCombine` with record which hold avro byte
and then shuffle the result. So there is no performce loss. This is also the
original logic.
