Multiple separate/non-chained aggregations in one query? about heroic HOT 3 CLOSED

No.

But for min/max/average in particular there is a special aggregation called spread that can be used to aggregate all of them at the same time. It is currently experimental and uses a special data type. Instead of [[<ts>, <number>], ...] it would look something like: [[<ts>, {"min": <number>, "max": <number>, "sum": <number>, "sum2": <number>, "count": <number>}], ...].

The feature you describe would be interesting to implement in the future, so I've marked this as an enhancement.

I've added documentation about our batch endpoint: http://spotify.github.io/heroic/#!/docs/api/post-query-batch

Do keep in mind that batches are much more inefficient than spreads for your use-case, since the data will still have to be fetched multiple times from the metric backend.

Thanks, just tried it out - works great!

For the multiple aggregations enhancement, the easiest(?) solution might be to add support for multiple queries instead. So instead of sending one JSON query object, I can pass an array of query objects. In that case the response would just be an array with the different result sets.

(This is actually how Kairos and OpenTSDB are doing it, sorry for being a bit ambiguous in original post)
