ok heres a working version, which supplies a pyarrow schema to when creating the pyarrow table. The difference is the parquet `field-id` (see [`PYARROW_PARQUET_FIELD_ID_KEY`](https://github.com/apache/iceberg-python/blob/4b15fb6fe0870071c5a23e95b811631877dd291b/pyiceberg/io/pyarrow.py#L192)) ``` from pyiceberg.catalog import load_catalog catalog = load_catalog(**dict(type="in-memory")) from pyiceberg.schema import Schema from pyiceberg.types import NestedField, StringType, ListType schema = Schema( NestedField(field_id=1, name="name", field_type=StringType(), required=False), NestedField( field_id=3, name="my_list", field_type=ListType( element_id=45, element=StringType(), element_required=False ), required=False, ), ) catalog.create_namespace_if_not_exists("test") tbl = catalog.create_table_if_not_exists("test.table", schema) import pyarrow as pa df_1 = pa.Table.from_pylist([ {"name": "one", "my_list": ["test"]}, {"name": "another", "my_list": ["test"]}, ], tbl.schema().as_arrow()) catalog.load_table("test.table").append(df_1) catalog.load_table("test.table").scan().to_arrow() import pyarrow as pa df_2 = pa.Table.from_pylist([ {"name": "one"}, {"name": "another"}, ], tbl.schema().as_arrow()) catalog.load_table("test.table").append(df_2) catalog.load_table("test.table").scan().to_arrow() ``` -- This is an automated message from the Apache Git Service.
