There's a [`Table.add_files` API](https://github.com/apache/iceberg-python/blob/5039b5d70644bc06c98349090912c6e9066d3ea1/mkdocs/docs/api.md#add-files) which supports directly adding parquet files. But it seems like the parquet files must have the same schema. You can also read all the parquet files into memory with PyArrow, merge the different schemas (using [pyarrow.unify_schemas](https://arrow.apache.org/docs/python/generated/pyarrow.unify_schemas.html)) and then write Arrow as Iceberg table. Maybe DuckDB works well here since `read_parquet` can union schemas, [see `union_by_name`](https://duckdb.org/docs/data/parquet/overview.html#parameters) and https://duckdb.org/docs/data/parquet/tips.html#use-union_by_name-when-loading-files-with-different-schemas -- This is an automated message from the Apache Git Service.
