Review comment:
Hey, is this right ? the logic is not equivalent:
HoodieRecord.HOODIE_META_COLUMNS_WITH_OPERATION ->
HoodieRecord.HOODIE_META_COLUMNS, i added the
HoodieRecord.HOODIE_META_COLUMNS_WITH_OPERATION because when flink turns on the
'changelog mode', there is another metadata field named '_hoodie_operation'
