atwam opened a new issue, #5354: URL: https://github.com/apache/arrow-rs/issues/5354
**Describe the bug** When importing a pyarrow RecordBatch, we instantiate a `StructArray`, then convert it to a `RecordBatch`. This loses the metadata from the original schema. This is not seen in the current tests, because pyarrow's tests for equality on schemas ignores metadata. https://github.com/apache/arrow-rs/blob/31cf5ce23febf076104f064358a24fe8af09ee4b/arrow/src/pyarrow.rs#L357-L358 **To Reproduce** ```python # In arrow-pyarrow-integration-testing/tests/test_sql.py:470 batch = pa.record_batch([f32_array], ["tensor"], metadata={b'key1': b'value1'}) b = rust.round_trip_record_batch(batch) assert b == batch # OK assert b.schema == batch.schema # OK assert b.schema.metadata == batch.schema.metadata # Fails ``` **Expected behavior** Imported RecordBatch's schema should keep its metadata. -- This is an automated message from the Apache Git Service.
