I thought the docs were very sparse, especially from a development perspective. I was wondering if they were using vectorization or doing record materialization at read time like Impala. Can't imagine they would get any performance out of it if they didn't do vectorization, as they already have to live within the constraints of java. Would also be interesting to see if they used code generation or the netty/unsafe APIs at all. Will be taking a closer look in the next few weeks to see if there are some good ideas we can incorporate into Drill.
