Andre Kohn created ARROW-18423: ---------------------------------- Summary: [Python] Expose reading a schema from an IPC message Key: ARROW-18423 URL: https://issues.apache.org/jira/browse/ARROW-18423 Project: Apache Arrow Issue Type: Improvement Components: Python Reporter: Andre Kohn
Pyarrow currently does not implement reading the Arrow schema from an IPC message. [https://github.com/apache/arrow/blob/80b389efe902af376a85a8b3740e0dbdc5f80900/python/pyarrow/ipc.pxi#L1094] We'd like to consume Arrow IPC stream data like the following: ``` schema_msg = pyarrow.ipc.read_message(result_iter.next().data) schema = pyarrow.ipc.read_schema(schema_msg) for batch_data in result_iter: batch_msg = pyarrow.ipc.read_message(batch_data.data) batch = pyarrow.ipc.read_record_batch(batch_msg, schema) ``` The associated (tiny) PR on GitHub implements this reading by binding the existing C++ function. -- This message was sent by Atlassian Jira (v8.20.10#820010)
