pitrou opened a new issue, #48846: URL: https://github.com/apache/arrow/issues/48846
### Describe the enhancement requested `ReadMessageAsync` takes a `body_length` parameter and reads Message metadata + body in one go, but the blocking version `ReadMessage` reads the body length from the Message and issues a second read for the body. We could add a `ReadMessage` overload that takes the body length as parameter and does a single read the async version does. It can then be used in the IPC file reader so that less IOs are issued (though it won't make a difference in the common case where the IPC file is memory-mapped). ### Component(s) C++ -- This is an automated message from the Apache Git Service.
