## Summary Support configuring Parquet compression codecs per column. This lets users keep a table-level codec such as ZSTD while overriding selected columns to another codec, including `none` / `UNCOMPRESSED`. ## Changes - Add column-level compression parsing for `parquet.compression#<column.path>` in the Paimon Parquet writer. - Extend the local Parquet writer wrapper to choose compressors per column chunk while preserving the existing global compression default. - Add a footer-based test that writes a default ZSTD file with one uncompressed column and verifies the stored column chunk codecs. ## Testing - [x] `mvn -pl paimon-format -Dtest=ParquetFormatReadWriteTest test` -- This is an automated message from the Apache Git Service.
