@nsyca No problem. We actually support `NOT IN` queries. We set the the
`PredicateSubquery.nullAware` flag to true if we encounter an `IN` subquery
expression. `NOT IN` is planned using a `NULL` aware anti-join in the optimizer.
I have written a blogpost/notebook on the current implementation and state
of subqueries in Spark 2.0 (including known issues): [SQL Subqueries in Apache
Spark
2.0](https://databricks.com/blog/2016/06/17/sql-subqueries-in-apache-spark-2-0.html)
