Andrey Mashenkov updated IGNITE-28389:
--------------------------------------
Description:
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).
