> We had discussions on the Apache Calcite [1] and Apache Drill [2] mailing
> lists regarding an equivalent for DISTINCT ON. The community seems to prefer
> the ANY_VALUE. This Jira is a placeholder for implementing the ANY_VALUE
> aggregate function in Apache Drill. We should also eventually contribute it
> to Apache Calcite.
