While scaling up machine learning at Instacart, Montana Low and Lev Kokotov discovered just how much you can do with the Postgres database. They are building on that work with PostgresML, an extension to the database that lets you train and deploy models to make online predictions using only SQL. This is super practical discussion that you don’t want to miss!

Gerhard & Frederic — **What do oranges & flame graphs have in common? (Ship It! #57)** Jun 17, 2022
Show notes

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.
