How We Cut Telemetry Queries to Under 10 Milliseconds

We built a telemetry pipeline that handles more than 5,400 data points per second with sub-10 millisecond query responses. The techniques we discovered while processing flight simulator data at 60FPS (frames per second) apply to any high-frequency telemetry system, from Internet of Things (IoT) sensors to application monitoring.

Here’s how we got our queries from 30 seconds down to sub-10ms, and why these techniques work for any high-frequency telemetry system.
