Maybe you should read this:

Julien Danjou pretends Gnocchi is able to eat 100k record per second. I
wouldn't bet on this, but that's probably enough for OpenStack.

Though the biggest bottleneck is probably the notification bus, not the
time series. I've heard that switching to kafka may help, but I'm really
not a fan of this "solution" (which IMO isn't one, as Kafka brings its
own set of problems).

Prometheus is already in Debian, and it's been there for the last 2
releases, so I'd be ok switching to it. However, you'd have to provide a
migration path for those already using Gnocchi.
