@Dandandan Thanks for the reply. If you read my second comment I think the main thing here is adding documentation about how using `ORDER BY` post joins may be necessary to get deterministic ordering for operations such as groupbys. I think this is somewhat known/implied for technologies similar to this, but its a gotchya that people may forget about and is probably worth mentioning. Maybe just a section in the SQL capabilities docs about the differences between DF and a typical SQL DB would be useful. Feel free to close this issue out at your own discretion. -- This is an automated message from the Apache Git Service.
