Once we have this in place, we can extend it with more functions for deriving metrics. Also, since it requires keeping a streaming window of data, we can interesting things...

One approach I started experimenting with is extending the batch endpoint with additional reducers that act as aggregations after the original query is assembled. I think its possible to reuse...

One major edge case to consider is if the node is configured with a different policy than the rest of the cluster. How do we decide when to update the...

Current state of module dependencies:  I think to mark this issue as finished there are still a few things left to do: - [x] Stop repackaging datastax - [...

@sming Not directly, although having this kind of data would help us make more informed decisions when prioritizing our efforts.

Actually, the HBase client [does support the emulator var](https://github.com/googleapis/java-bigtable-hbase/blob/master/bigtable-client-core-parent/bigtable-client-core/src/main/java/com/google/cloud/bigtable/config/BigtableOptions.java#L294).

As points of comparison, [OpenTSDB](https://influxdbcom.readthedocs.io/en/latest/content/docs/v0.8/api/query_language/) has its own query language. InfluxDB has a [SQL-like](https://docs.influxdata.com/influxdb/v1.7/query_language/) query language and supports reads through a specific endpoint. There are actually only a handful of...

For the adapter, we still have to translate the PromQL query into something Heroic understands, right? I just don't think we should support multiple DSLs long term. If the experimentation...

@dmichel1 experimented with t-digests and bucketed histograms recently: > The t-digests are really nice since you don't have to worry about setting bucket boundaries yourself. This would require heroic to...

So there are two places that `Application.get_env/3` is used, and I think its worth making a distinction between them. One is [in the router](https://github.com/hexedpackets/trot/blob/051373446ec72e6c0ef6a953bdc56c12aef96e53/lib/trot/router.ex#L43-L49), which it sounds like is what...
