Learn how to manage and optimize validation cost budgets in Kubernetes Custom Resource Definitions (CRDs) through this technical conference talk from Red Hat engineer Joel Speed. Explore the fundamentals of Common Expression Language (CEL) for complex validations before diving into practical examples of CEL validations that trigger API server rejections. Understand how runtime cost calculations work, why certain validations can exceed the allowed budget by over 100x, and discover effective strategies for building APIs that stay within cost limits. Master the key factors affecting CEL runtime costs and gain practical knowledge for implementing efficient CRD validations that meet performance requirements.
