Support Apache Arrow memory format as interface between the SDKs and the Alteryx Engine

[cam_w]

Transfer of records from Python SDK RecordRef seems to be slow sending large amounts of data to the Alteryx Engine (e.g. discussion here). Although unclear of the exact specifics, it seems that there's a copy and convert process in play.

Apache Arrow appears to be addressing this issue, and the roadmap and specs are impressive! It seems like (again I have no understanding of the Alteryx Engine specifics) that something like this would be excellent for expanding SDK use cases as well as for other connectors such as the Apache Spark connector.

And it looks like it'd be fun to build into Alteryx! 🙂
