Akka Unplugged - The Anti-Patterns That Kill Performance

Discover the most common Akka anti-patterns that sabotage performance and learn proven strategies to fix them in this 42-minute conference talk from Scala Days 2025. Explore real-world mistakes encountered across dozens of projects that transform Akka's powerful capabilities into slow, buggy, and unmaintainable systems. Examine specific anti-patterns across Akka HTTP, Akka Actors, Akka Persistence, and Akka Clustering through concrete examples and live demonstrations that reveal how overcomplicated architectures emerge from misunderstanding this flexible but demanding technology. Learn to identify performance killers in your own codebase, from misused HTTP endpoints and poorly designed actor hierarchies to persistence pitfalls and clustering complications. Master practical remediation strategies that leverage existing Akka capabilities rather than requiring expensive infrastructure additions or complete rewrites. Understand how disciplined application of proven patterns can deliver significant improvements in development speed, memory consumption, system stability, and maintainability by working with Akka's design principles instead of against them.
