Deterministic Java workflows guarantee replay consistency when processes resume after interruptions. You implement them using TaskOrchestrationFactory and TaskActivityFactory with the Durable Task Java SDK, ensuring explicit activity boundaries and external events.

Long-running Java business processes support built-in retries and state persistence. The Durable Task Scheduler enables pattern-based orchestration, including function chaining, fan-out/fan-in, and sub-orchestrations for reliable execution.

Durable task orchestrations run in on-premises, cloud, or containerized deployments. The Java SDK connects via Azure-managed connectors to your scheduler endpoint or a local DTS emulator for environment flexibility.

Java workflow orchestrations handle human interaction and monitoring through supported orchestration patterns. You implement these patterns via the Durable Task Java SDK, managing external events, timers, and eternal orchestrations.

Java orchestration determinism requires strict adherence to execution rules. Violations occur when workflows perform non-deterministic operations outside explicit activity boundaries, timers, retries, or external events managed by the Durable Task Scheduler.

You need a standard Java runtime and the Durable Task Java SDK artifacts to use the Durable Task Scheduler. Install the SDK, implement orchestration factories, and run against a local DTS emulator or your scheduler endpoint.
