I've been a developer in Spotify's analytics and data infrastructure team for the past two years. I've seen the team grew from two people doing basic log collection and reports to being over 20 people with a 120+ node Hadoop cluster containing petabytes of data. Like many other backend services at Spotify, almost all of our data pipeline, as we call it, is written in Python. I'm one of the architects and main contributors behind the Luigi data processing framework for Python recently open sourced by Spotify.
