When I started Baselime, one of the key shifts I noticed was the emergence of ClickHouse as a database for analytics, and I quickly realised it would be extremely good for high-cardinality and dimentionality data, which are two essential properties of data used for observability. That’s why the Baselime data layer is powered by a self-hosted ClickHouse cluster.

When the ClickHouse team invited me to speak at their London meetup, I was so excited to share what we’d learned building an observability platform on top of ClickHouse, for our ingestion pipelines to our database schemas, etc.
