The Doctor Is In–Quick First Aid for Broken ClickHouse® Clusters

Properly managed ClickHouse servers are well-behaved, but every cluster runs into problems at some point.

In this webinar, we’ll introduce common issues that require admin intervention or even application changes. Topics include too many connections, too many parts, lost replicas, stuck mutations, and too many detached parts on startup. In each case, we’ll explain the problem, show you the symptoms, and give you the standard cures.

There will be extra time for questions, so bring your favorites. We’ll be happy to offer opinions.
