November 2024 performance-focused month for argoproj/argo-workflows. Key delivery: implemented Workflow Template Caching for Faster Validation by introducing informer-based caching for workflow templates and cluster workflow templates, coupled with adjustments to client initialization and server configurations to leverage the new caching layer. Commit reference: f22ae3b87a6cf5c0b7131bb49da6dea097edee0e (perf: Add workflow template informer to server #13672). Business value: reduces validation latency and read load for templates, enabling faster validation cycles and improved scalability as template usage grows. Lays groundwork for broader caching strategies across the workflow engine. Major bugs fixed: none reported this month. Overall impact and accomplishments: delivered a targeted performance enhancement aligned with reliability and scalability goals, demonstrated end-to-end changes from server-side informers to client usage, and established patterns for future caching improvements. Technologies/skills demonstrated: Go, Kubernetes informers, client/server initialization tuning, caching strategies, performance instrumentation, and code review discipline.
