…skipping
Data skipping translated filters over cast/multiply/divide transformations
by re-applying them to column min/max stats, assuming they preserve ordering.
Narrowing numeric casts wrap around in non-ANSI mode, collation-changing string
casts re-sort on Spark 4, and negative multiply/divide factors reverse
ordering, so the translated bounds could silently prune files containing
matching rows.
- isCastPreservingOrdering now requires Cast.canUpCast for numeric pairs and
identical string types (collation-aware on Spark 4) for string pairs
- Multiply/Divide transformations now require a strictly positive numeric
literal factor
Non-order-preserving shapes fall back to no pruning for that predicate.
Fixes #19445
