@jiangxb1987 will reorg the existing Spark SQL doc. We can think about how to put this into the new version of Spark SQL doc.

I don't think we would merge this to Spark docs right? I don't think this is an efficient way to discuss a design document if that's the intent

This is not ready yet. Eventually, we need a document for vectorized Python UDF

Sorry for the late reply.

@srowen At this point I would like to have feedback on the design doc so we can move forward with implementation or a formal Spark docs if people prefer. What do you think is a best way to discuss design document?

Do people prefer google doc? I can do that too.

I feel google doc is easier to review and discuss

Thanks all for the advice. I've put this in a google doc.

Close this in favor of the google doc.
