Thanks (also to Mike) for sharing. I can't comment about your specific use-case, but I imagine that unless your latency requirements are very demanding, graphite can play nicely here. Its rather expressive querying allows you to aggregate timeseries data pretty easily. Of course, Graphite is primarily used for monitoring and trending, but it's not limited to this use-case. Alerting isn't something it's particularly great at though, but there are other tools that plug in there.

Not trying to diss redis, I'm using redis as well and love it, but was just curious since you mentioned time-series data.
