What do oranges & flame graphs have in common?

Today we are talking with Frederic Branczyk, founder of Polar Signals & Prometheus maintainer. You may remember Frederic from episode 33 when we introduced Parca.dev.

This time, we talk about a database built for observability: FrostDB, formerly known as ArcticDB. eBPF generates a lot of high cardinality data, which requires a new approach to writing, persisting & then reading back this state.

TL;DR FrostDB is sub zero cool & well worthy of its name.
