This repository contains illustrative example code that accompanies ClickHouse blog posts, talks, and documentation. The examples are meant to be cloned and run locally by developers evaluating ClickHouse. They are not hosted services, and nothing here is deployed to a live, internet-facing environment by ClickHouse.
Because of this, the practical risk of most dependency vulnerabilities (CVEs) reported against these examples is low: there is no long-running, internet-exposed service for an attacker to reach. The examples are nonetheless useful references, so we keep them available rather than deleting them.
Treat every example as a starting point, not production-ready code. Before using any of it in a real deployment, audit and update its dependencies and review it for your own security requirements.
