Currently we always store datapoints as they come in, and query at full resolution. With certain kinds of sensors this can become heavy.

We should implement downsampling for historical data, and set a retention policy on the full resolution tables

Why don't you simply pump the data into RRDs? I mean, thinning out metrics is a problem that has been solved generically pretty well. Why reinvent the wheel?

EDIT: Ah, my bad. The sole idea is to use InfluxDB, I take it.
