JingsongLi opened a new pull request, #8279:
URL: https://github.com/apache/paimon/pull/8279

   ## 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`
