Since you want to quickly revise topics in a new complicated subject, I'd suggest simply slowing down and writing really thoughtful notes on the subject. Use elements of recall to really get a picture of where your understanding is at, itll help you build the lattice of your knowledge and that lattice will be strengthened when you review your notes.
I dont think cheatsheets are helpful personally. Unless you are just talking about syntax.
Also specific methods might be worth a look down the line, but initially I dont think it makes sense.
Thanks for the info - very helpful. Are there any specific use cases that you can point to? I dont doubt that the tech is robust, just that the use cases arent too obvious right now.
What I mean is - and I get that these are somewhat different technologies - snowflake offers a more seemingly comprehensive platform for data by aggregating it and focusing the product on that aggregation for future use.
Compared to Cockroach DB which seems like a niche SQL replacement?
