> 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

> Priority: Major
> Fix For: 4.0.0
>
>
> 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.
