## Summary - Support `data-evolution.nested-field.enabled` for native Parquet table reads and partial-column writes. Reconstruct physical ROW schemas from dotted `write_cols` paths and apply Java's one-level partial-write validation. - Select the latest file per nested leaf when merging row-ID groups, preserve parent and child ROW nullness under nested projections and historical schemas, and read only the provider children needed for composition. - Support nested SET paths in row-ID updates, use leaf IDs for nested row-ID conflict checks, and keep projected scan groups when their files contain nested write paths. The behavior follows Java's `RowType.projectByPaths`, `DataEvolutionReadPlanner`, `DataEvolutionRow`, and `RowIdColumnConflictChecker`. The change adds 2,184 lines, including focused unit and Parquet end-to-end regression tests. ## Verification - `cargo test -p paimon --lib data_evolution_ --quiet` (144 passed, 1 ignored) - `cargo test -p paimon --lib table::data_file_reader::row_tests --quiet` (10 passed) - `cargo test -p paimon --lib table::table_commit::tests --quiet` (102 passed) - `cargo test -p paimon --lib table::table_scan::tests --quiet` (107 passed) - `cargo fmt --all -- --check` - `cargo clippy --locked --all-targets --workspace --features fulltext,vortex -- -D warnings` - `cargo +1.94.0 check --locked --workspace --all-targets --all-features` -- This is an automated message from the Apache Git Service.
