### Feature Request / Improvement Support a table transaction where the user can directly supply the file metadata, similar to the [Java Interface](https://javadoc.io/doc/org.apache.iceberg/iceberg-api/latest/org/apache/iceberg/AppendFiles.html). This is a lower-level operation than what is covered `add_files` operation and it covers several additional use-cases. For example: 1. **Implicit Partitioning**: Iceberg does not require that partition values actually be stored in the actual parquet files. And in some cases, it may be useful to define a partiion value of a parquet file after it has been written (or to intentionally exclude to e.g. minimize storage). However, `add_files` does not currently support an option. 2. **Pre-calculated statistics**: Calculating parquet statistics (e.g. column bounds) can be a somewhat resource intensive operations. If this has been pre-calculated by the user, it would be faster to update the manifest file directly. -- This is an automated message from the Apache Git Service.
