---------------------------------------

Thanks, Ildar. A dml test: scan-delete-btree-secondary-index-open is a good place to start.

> Currently, index entries (SK, PK) are not deleted on an open-type secondary index. This
issue was not surfaced due to the fact that every search after a secondary index search needs
to go through the primary index lookup. Therefore, un-deleted entries were removed during
this Pidx lookup.
> Now, we have an index-only plan that can skip the Pidx lookup after a Sidx search. Therefore,
the query result is not correct anymore.
