costas-db opened a new pull request, #3830: URL: https://github.com/apache/parquet-java/pull/3830
### What changes? Use `ColumnPath` instead of flattened dot strings for dictionary metadata and cache keys. Add a regression with ordinary string columns whose distinct paths (`["a.b"]` and `["a", "b"]`) previously collided. ### Why is this needed? Flattening both paths to `"a.b"` lets one column overwrite the other, so a dictionary request can return values from the wrong column. The change preserves path-component identity in memory and does not alter the Parquet format. ### Tests - `TestParquetWriter` (32 tests) - Spotless - Apache RAT Fixes #3828 -- This is an automated message from the Apache Git Service.
