Handle grafana queries directly

[jeffpierce]

It'd be nice to simply handle queries from Grafana directly rather than needing graphite or graphite-API as a middleman.

Let's look at how feasible this might be.

What is the transform that Graphite does to requests, incoming and returning? Is the data very similar?

[jeffpierce]

It does a lot, based on the functions asked for. We'd have to implement the functions listed here, at minimum:

Hm, that is indeed a lot. Maybe the Unix philosophy of "do one thing well, and connect with pipes" applies here.

[jeffpierce]

Yep. That's more of a pipe dream on my end of things, given that graphite-api is now the slowest part of the grafana -> graphite-api -> cassabon chain.
