@kevinjqliu It is strange to me that in PyArrow there is [pa.unify_schemas(...)](https://arrow.apache.org/docs/python/generated/pyarrow.unify_schemas.html) which is able (I double-checked) to unify **nested schemas** (even with type promotions). But there is no "dual" functionality to cast, concat, read or to do something different with corresponding **data** in `pa.Table`. None of e.g. [pa.Table.cast(...)](https://arrow.apache.org/docs/python/generated/pyarrow.Table.html#pyarrow.Table.cast), [pa.concat_tables(...)](https://arrow.apache.org/docs/python/generated/pyarrow.concat_tables.html), [pa.concat_tables(...)](https://arrow.apache.org/docs/python/generated/pyarrow.concat_tables.html), [pa.parquet.read_table(...)](https://arrow.apache.org/docs/python/generated/pyarrow.parquet.read_table.html) is working. -- This is an automated message from the Apache Git Service.
