Welcome to the February ClickHouse newsletter where we round up what’s been happening in the world of real-time data warehouses in the last month.

This month, we have a deep dive into ClickHouse’s internals, the Grafana v4.0 plugin, and the 24.1 release with the experimental Variant type.

Inside this issue

Our featured community member this month is Benjamin Wooton, founder & CTO of Ensemble, a company that helps businesses deploy real-time data, analytics, and AI platforms based on ClickHouse.


Benjamin is a passionate advocate of ClickHouse and you’ll often see him engaging in discussions about real-time data warehouses and similar topics on LinkedIn and Twitter.

He’s also written several blog posts over the last few weeks, covering various use cases. In the most recent one, Benjamin comes up with the optimal way of allocating consultants to projects based on their skills using Google’s OR-Tools library mixed in with some ClickHouse queries. He also uses a similar toolkit to come up with a solution to a traveling salesman type problem.

And if that’s not enough, Benjamin also presented Building Real-Time Analytics Systems with ClickHouse at the ClickHouse London meetup this week.
