Subject Re: Seeking interest and a champion for bifroest - a backend for graphite-web, on Apache Cassandra
Date Tue, 07 Oct 2014 14:20:15 GMT
Hi,

am I looking at the right pull requests with graphite-project/carbon#210
and #216?

Quite interesting. Sadly, I don't think I could provide exactly that python
API with our existing storage input frontend.

Just look out for the issues we fixed in
https://github.com/graphite-project/graphite-web/pull/698 :)
