Refinery and EMA Sampling
Refinery is Honeycomb’s sampling proxy, which our largest customers use to improve the value they get from their telemetry. It has a variety of interesting samplers to choose from. One category of these is called dynamic sampling. It’s basically a technique for adjusting sample rates to account for the volume of incoming data—but doing so in a way that rare events get more priority than common events. Honeycomb’s query engine can compensate for sampling rates on a per-event basis.
