This document discusses using ClickHouse for experimentation and metrics at Spotify. It describes how Spotify built an experimentation platform using ClickHouse to provide teams interactive queries on granular metrics data with low latency. Key aspects include ingesting data from Google Cloud Storage to ClickHouse daily, defining metrics through a centralized catalog, and visualizing metrics and running queries using Superset connected to ClickHouse. The platform aims to reduce load on notebooks and BigQuery by serving common queries directly from ClickHouse.
