FQL is interesting because it focuses on transactional systems and eliminating the need for an ORM in applications. I feel many of the SQL replacement projects like PRQL and Malloy instead come from the analytics side of the house, which doesn't really help application developers at all. (But does raise the question, how do I do analytics in Fauna? Do I ETL to a traditional warehouse system?)

That's a good question. If you need to ETL to a traditional data warehouse in order to do analytics, wouldn't you need an ORM, which is exactly what they're trying to avoid? (Also note that it's usually ELT instead of ETL these days, like if you're using Snowflake)

Or is Fauna a hybrid transactional/analytical database so you can do analytics in it using FQL? (Maybe the long-awaited possibility of true hybrid databases is real?!) But then you'd need to train all of your business intelligence analysts on FQL, which would be a drawback.
