> Mapping test for partition pruning looks incorrect.
> See `modules/sql-engine/src/test/resources/mapping/test_partition_pruning.test`
> Explain plan contains TableScans with `predicate: false`. 
> In case of `always false` predicate, the scan operation returns nothing and can be replaced by an empty source (e.g. with an empty Values node).
