It's quite odd that the original code didn't take prewhere into account...

If those are actually needed, we need to place a mental pin here that after backporting prewhere+row_policy we'll need to add hasRowLevelFilter here as well.

This test seems to be passing on the current Antalya branch:

test_database_iceberg/test.py::test_cluster_joins PASSED  

Is it expected?

[ianton-ru]

Nice catch, test doesn't cover case with local right table, thanks!

[ianton-ru]

And not on cluster...
