Fabian Reinartz aabb21f4b9 Add shard series set test 2016-12-19 11:44:11 +01:00
Fabian Reinartz e561c91d53 Implement proper buffered iterator 
This adds a proper duration based lookback buffer for series iterators
to allow advancing sequentially while remaining able to calculate time
aggregating functions such as `rate` backwards.

It uses an array ring buffer to minimize heap allocations for
potentially hundreds of thousands of series for a single query.
