DAX table or Query table

Hi all
I would like to hear your opinion on this subject:
Which is faster when uploading new data and refresh it? 
1. DAX table (which is an union of tables)
2. Query table (which is an append table from 2 or 3 queries)
Can i ask why?
Thanks a lot for your answers.
Best regards

Pedro

Re: DAX table or Query table

Hi @pedromooji 

 

In general, the best practice is to create all tables, columns in Power Query, you will get better performance and compression most of the times, plus you do not need to load all the tables, just the appended one, where if you opt for Dax union solution you will need to load all tables to your model and this will increase the size.
