Pissed me off so much. Only thing close to Google's F0 RDBMS on the market, at a reasonable rate, and the beginning of a good offer to enterprises. Then, "poof!" It's a good example of why I tell companies to not put anything critical into something from a startup. If they do, better have a synchronized, backup option tested and ready to go.
"why they are moving towards a SQL-ish vs key-value interface..."
That's easy: most databases and buyers use SQL. Key-value is preferred by startups & non-critical, side projects in big companies you see here a lot but aren't representative of most of the market. Need first-rate, SQL support. I think EnterpriseDB shows that it's also a good idea to clone a market leader's features onto alternative database.
Did you mean F1 (instead of F0)?
There are really not a large number of options here anymore with the departure of FoundationDB from the market. CockroachDB might be an option in a few years, though I'm still confused why they are moving towards a SQL-ish vs key-value interface...
