Subquery versus Output Table
I am always looking to optimize my dataflows and was curious if it was better to have multiple output tables in a dataflow or less output tables by utilizing subqueries? For debugging and readability it is nice to have multiple output tables but I do not want to do this if it will have a negative impact on performance.
Thanks in advance for your responses.

hey @cwolman!
For larger datasets at least, having multiple transforms is a good way to go, in my experience subqueries seem to bog down a bit for the larger sizes.
For smaller datasets, do it either way, whatever works best for you.
Seems like you're on the right track!
