### Purpose Add Parquet map shredding support for `MAP<STRING, T>` columns. This allows selected map columns to extract hot keys into independent physical Parquet columns while preserving the original logical map schema for readers. The feature is controlled by `map.shredding.*` options, aligned with the existing `variant.shredding.*` naming style. It also adds a focused round-trip test and a storage benchmark to validate the storage benefit. ### Tests - `mvn -pl paimon-api,paimon-format -Pfast-build -DskipTests compile` - `mvn -pl paimon-format -am -Pfast-build -DfailIfNoTests=false -Dtest=ParquetFormatReadWriteTest#testMapShreddingRoundTrip,MapShreddingStorageBenchmark test` - `git diff --check` close #7876 -- This is an automated message from the Apache Git Service.
