> Iceberg table update and merge is implemented using split update early by HIVE-26319 and HIVE-26385.
> Without split update early deleted records has to be buffered in memory  when updating iceberg tables. With split update early deleted records are processed by a separate reducer and no buffering is required. The ReduceSink operator also sorts the records.
