Migration to ClickHouse: Practical Guide

At LifeStreet we needed to scale our real-time ad analytics platform to multiple petabytes. We evaluated and used a number of open-source and commercial solutions, but they either were not efficient enough, or too expensive. When ClickHouse was released into the open-source community, we quickly realized its potential and started our implementation and migration project. It was a long and winding road but it finally worked out. In this presentation I will talk about the most important lessons we learned and discuss the best application design practices for building a large-scale platform based on ClickHouse.
