I have no hands-on experience with the HTTP UDFs model but am intrigued by the approach. Thank you for laying out your thoughts. Had some thoughts and questions. #### Things I really like: - Clearly a remote invocation approach makes managing 3rd party dependencies a breeze - Clean and repeatable model for creating UDFs. I think this approach would be fairly intuitive for any Python user. #### Concerns/Questions (mostly because of my lack of experience here) - Where would the HTTP server be hosted? Scheduler? Single Executor process? Multiple Executor processes? An entirely new process? - Wouldn't it make more sense to have that communication channel be Arrow flight instead of HTTP? - Seems like this would introduce a large performance hit having to make an external (data movement) remote invocation for each RecordBatch since the data would need to be moved to the HTTP UDF service running on another host. -- This is an automated message from the Apache Git Service.
