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!
