> How does Spanner not satisfy that itch? Not ordered matters?

I was probably unclear in my previous comment. Spanner is great! (And Spanner is ordered). The particular aspect of FDB that I miss is what some of our old customers called "the bottom half of a database" or "a database construction kit". In fact FDB was an awesome modular building block for all kinds of distributed systems, not just databases. We hacked up prototypes for a whole bunch of these but sadly never got around to releasing them.

Spanner is a full-fledged enterprise grade database with opinions about your data model, query language, types, etc. For the vast majority of customers, that's much more useful than what FDB provided. But for me as somebody who enjoys kicking around silly new ideas for distributed systems, it's a bit less fun.
