> Reporter: Gabor Kaszab

> Iceberg metadata holds an equality field ID list for the equality-delete
> files. It's possible to have a different equality field ID list for different
> equality-delete files, for instance one file deletes by columnA while another
> file deletes by columnB.
> When you have such a table you should have multiple layers of ANTI JOINs, one
> join for each equality field ID list.
