ETL joining causes an output dataflow that is too big?
I am very new in using Domo, so hopefully I can explain my situation well.
I have three datasets that have different column names and structures, even though each dataset has same columns too, like 'Employee Name' and 'Employee ID'.
I tried to join them (using inner join) and run preview with 10k limit, but it showed the message 'Preview took too long to respond. Try running with less data."
I then ran the preview with 1k limit and it worked.
So I saved and run the dataflow, but it kept on running without showing any result, and my output dataflow ended up with 0 rows.
Anyone can advise what am I doing wrong here and what can I do to fix this? Thanks a lot.
