The end of event-based architectures? Orchestration with Temporal
summary
A concrete demo of building a videogame-store order workflow using the Temporal SDK (Java/Kotlin), running a Docker Compose Temporal cluster with Postgres and Elasticsearch persistence. The workflow covers reserving inventory, awaiting a payment webhook, capturing payment, updating shipping with tracking numbers, and uses durable task-queue workers with signals and queries, automatic retry policies, saga compensation for unrecoverable failures, and an in-memory Temporal test SDK; a cloud tier price of about $25 for ~1M actions is mentioned.
