I recently gave a talk at GDG Devfest Ukraine about our use of gRPC & Kubernetes at Kausal. In the talk we discussed basic concepts of gRPC: Protocol Buffers, code generation and HTTP 2.0.

This blog post is part 2 of a series on the recent talk I gave at PromCon 2017 in Munich about what we’ve learnt running Cortex, our open source, horizontally scalable Prometheus implementation, for over a year. Part 1 can be found here. In this blog post we discuss how we handled queries of death, recording rules and alerts, and long tail write latency.
