---------------------------------
Summary: Introduce copy-on-write DML implementations for Iceberg
tables
Key: HIVE-26630
URL: https://issues.apache.org/jira/browse/HIVE-26630
Project: Hive
Issue Type: Improvement
Reporter: Ádám Szita
Assignee: Ayush Saxena
Hive currently only supports merge-on-read approach when doing
delete/update/merge operations on Iceberg tables. From performance point of
view this has the advantage on the write side and disadvantage on the read side.
We should create a copy-on-write implementation for these where the pro's and
con's are inverted which might suite better certain use cases.
