> Key: ARROW-14470

> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python

> Labels: feather

> On the C++ side, the Feather V2 Reader wraps the IPC RecordBatchFileReader, which accepts IpcReadOptions which can control the use of threads (and the default memory pool and some other options).
> On the Python (cython) side, those options are not passed through. As a consequence the {{use_threads}} keyword only disables multithreading in the conversion from arrow table to pandas DataFrame, and not the actual reading. As a follow-up on ARROW-13317, we can actually make this keyword control both.p
