I just wanted to add a note here to say that I have dedicated time now to help with this effort. I think we can break this work down into phases and the logical starting point (pun intended) would be to decide on how we want to represent the various types of subquery in the LogicalPlan. Once we have that we can create separate issues and PRs for SQL query planning, DataFrame API, logical plan optimizations, and implementing the physical plans. I am going to start by reviewing Apache Spark's logical plan for subqueries and then will put a proposal up. I'm not sure if this will be in the form of a PR or a Google document yet but I will share the proposal here, probably early next week. -- This is an automated message from the Apache Git Service.
