Use column dictionaries to prune row groups after footer-statistics filtering. Support comparison, set, prefix and NaN predicates, and cache decoded dictionaries within each row group. Keep row groups when encoding metadata cannot rule out plain fallback or field IDs and types cannot be resolved safely. Preserve file-relative row positions and row IDs after pruning. Share physical-value conversion with Parquet metrics and add tests for predicate handling, type promotion, mixed encoding, splits and invalid dictionary pages. -- This is an automated message from the Apache Git Service.
