Yes, this is exactly it. Given that turbopuffer itself is built on the idea of object storage + stateless cache, we're all very comfortable dealing with it operationally. This design is enough for our needs and is much easier to be oncall for than adding an entirely new dependency would have been.

IMO this is the ideal way to engineer most (not all) systems. As simple as your needs allow. Nice work!
