-------------------------------------
Summary: Iceberg integration: disable update and merge iceberg
table when split update is off
Key: HIVE-26417
URL: https://issues.apache.org/jira/browse/HIVE-26417
Project: Hive
Issue Type: Improvement
Components: File Formats
Reporter: Krisztian Kasa
Assignee: Krisztian Kasa
Fix For: 4.0.0
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.
