## Summary - Add native Mosaic data-file writes for ordinary append and primary-key Paimon tables, including input changelog files. - Match Java Paimon Mosaic writer options and type validation: Zstd only, bucket count, block size, statistics columns, and unsupported Paimon types. - Write selected Mosaic statistics into manifest value stats, preserving column order and null counts for file pruning. - Document Mosaic table writes and add end-to-end coverage for append, primary-key, partitioned, changelog, rolling, file-index, pruning, temporal, scalar, and collection cases. ## Java parity Compared with `MosaicFileFormat`, `MosaicWriterFactory`, `MosaicRecordsWriter`, and `MosaicSimpleStatsExtractor`. In particular, the Rust writer rejects `ROW`, `MULTISET`, `VECTOR`, `VARIANT`, and `BLOB`; handles timestamp(0) with Mosaic millisecond storage; and applies the same writer options and selected statistics semantics. ## Tests - `cargo test -p paimon --lib mosaic_write::tests -- --nocapture` (12 passed) - `cargo test -p paimon --lib mosaic_table_write_tests -- --nocapture` (16 passed) - `cargo fmt --all -- --check` - `cargo clippy -p paimon --all-targets -- -D warnings` -- This is an automated message from the Apache Git Service.
