alamb opened a new issue #86: URL: https://github.com/apache/arrow-datafusion/issues/86
*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-6892 Currently we have code in the SQL query planner that wraps aggregate queries in a projection (if needed) to preserve the order of the final results. This is needed because the aggregate query execution always returns a result with grouping expressions first and then aggregate expressions. It would be better (simpler, more readable code) to always wrap aggregates in projections and have an optimizer rule to remove redundant projections. There are likely other use cases where redundant projections might exist too. -- This is an automated message from the Apache Git Service.
