I am working with tables from a postgres database, I have these queries;
1-the bases have 4 and 16 millions of regristos
what steps do i have to do to work on a data model?
i want a model to be able to design the transformation, groupings, joins etc.
I am passing a model of what I have put together.
The database reading node, has a exesivamtne long time, I want to shorten it to make the model and then leave it running… (as I am very new I have a lot of errors and mistakes to correct).
can be in English or Spanish.
Thank you for the contribution.
