Hi, all. I'm very new to Apache Drill.
I'm quite interest in Drill query execution's implementation. After a little bit of source code reading, I found it is built on a processing model quite like a data-centric pushed-based style, which is very similar with the idea behind the Spark whole-stage codegen improvement(jira ticket https://issues.apache.org/jira/browse/SPARK-12795) And I wonder is there any detailed documentation about this? What's the consideration behind of our design in the Drill project. : ) Regards, Qiaoyi
