Day 9. Delta Lake
Signed up for a 10 day trial of O'Reilly to read the first 5 chapters of Delta Lake: Up and Running which actually seems to talk about the various processing tables etc and that the gold layer may actually be constructed in a star schema, details lacking everywhere else. Did a few more videos on Module 2 of the Databrick Engineer V3 course before they took it offline for maintenance, without any warning. Bit off. Signed up for the Community Edition of Databricks – seems the cluster twice as powerful as the one I've been using, so good for tutorials and such like, though the interface seems a bit outdated.
