> 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.
