User management is a key problem in any analytic application. Fortunately, ClickHouse has a rich set of features for authentication and authorization. We're going to tell you about all of them. We'll start with the model: users, profiles, roles, quotas, and row policies. Then we'll show you implementation choices from XML files to SQL commands to external identity providers like LDAP. Finally, we'll talk about features on the horizon to improve ClickHouse security. There will be a sample code plus plenty of time for questions. Join us to learn how to manage your users simply and effectively. 

Logs may be looked down upon by today’s observability thought leaders, but there is a reason they are the first pillar of observability: there’s a relevant log message at the end of almost every debugging journey! Collecting those logs from applications and infrastructure in a standard format is now trivial thanks to the OpenTelemetry Collector, and we get to keep it in the same format — and potentially the same database — as our other telemetry signals like traces, metrics, and profiles.
In this webinar, we’ll show how to use the OpenTelemetry Collector to gather all application and cluster logs from a Kubernetes cluster. We’ll use ClickHouse to store and query our logs and Grafana to visualize trends. By the end of the session, you’ll have everything you need to standardize your cluster logs on the most forward-looking format available today: OpenTelemetry.
