Delicious Play recipes for real world
summary
Shows concrete solutions: uses Play iteratees/enumerators to get TCP backpressure into HTTP, implements bounded non‑blocking mailboxes (example size 100) to drop old events instead of crashing, runs millions of devices and months‑long jobs as actors with Akka cluster sharding and event sourcing persisted to Cassandra, and streams page fragments to the browser with a BigPipe-style streaming format. Examples are real deployments (LinkedIn, precision farming) and the patterns are proven to avoid crashes and regain responsiveness.
