The Databricks Certified Data Engineer Professional exam most questions are too long for those English as second language. Not enough time to read through the questions and sometimes hard to comprehend
I strongly agree with you. There is not a Spanish version of this exam. Those exam are long even for native speakers just imagine for people with English as a second language. For instance, since Amazon does not have a Spanish version, they took this...

I'm new to databricks. (Not new to DB's - 10+ year DB Developer).How do you generate a MERGE statement in DataBricks? Trying to manually maintain a 500+ or 1000+ lines in a MERGE statement doesn't make much sense? Working with Large Tables of between...
In my opinion, when possible MERGE statement should be on the primary key. If not possible you can create your own unique key (by concatenate some fields and eventually hashing them) and then use it in merge logic.
