Common Expression Language (CEL) is a fast, portable, and safe expression language designed for embedding in performance-critical applications. It evaluates expressions in nanoseconds to microseconds with predictable costs, making it ideal for use cases like API authorization rules, list filters, and validation constraints on protocol buffers. CEL works best in scenarios where expressions are evaluated frequently but modified infrequently, such as HTTP request security policy evaluation.
