Integration of Distributed Real-time Data Computing in a Web App
summary
Claim: Playframework plus Scala use Futures and Iteratees to turn distributed, real‑time computations into a nonblocking stream to the browser. Implementation uses Play 2, Scala, Akka/ Mongo for telemetry, and server‑sent events to push incremental results. The app renders hundreds of charts from terabytes of financial data by sequencing futures into interleaved enumerators so each chart appears as soon as it’s ready. Demo shows the pipeline working end to end with per‑chart latency and progressive UI updates.
