The End of Event-Based Architectures? Orchestration with Temporal
summary
A live-coding demo builds an online videogame order system using Temporal (open-source from Uber) with Java/Kotlin, Spring and Docker Compose to show how Temporal workflows can replace event-driven choreography. It demonstrates durable workflows across restarts, activities on named queues, activity stubs with timeouts, signals and queries for payment webhooks and state inspection/update, search-attributes for visibility, retries and saga-style compensations under a one-in-three failure simulation, persisting workflow state in Postgres/Cassandra and tests with the Temporal testing SDK.
