Temporal is a microservice orchestration platform which enables developers to build scalable applications without sacrificing productivity or reliability. Temporal server executes units of application logic, Workflows, in a resilient manner that automatically handles intermittent failures, and retries failed operations.
Temporal is a mature technology, a fork of Uber's Cadence. Temporal is being developed by Temporal Technologies, a startup by the creators of Cadence.
Learn how to use Temporal on the docs site.
Partial implementation of all components that make up a Temporal SDK - Worker, Client, Workflows, and Activities
- Workflows
- Scheduling timers
- Scheduling (non-local) Activities
- Cancelling timers and Activities
- Signals
- Activities
- Heartbeats
- Cancellation
- Context
- Client
- Workflow client
- Service client (for administration)
- Worker
- Basic logging and tracing capabilities
- Polling on a single non-sticky task queue
Notably these features are missing:
- WF History pagination (only short Workflows are supported ATM)
- Sticky queues (meaning Workflows are not cached and are replayed from the beginning each time a new event comes in)
- Telemetry
- Workflow versioning
- Workflow cancellation
- Query support
- Local activities
- Side effects
- Windows support
NOTE: The API is considered unstable and may change at any time. While in alpha we are gathering feedback from developers about the usability and ergonomics of the API. To provide feedback please open an issue and feel free to talk to us on the community slack channel.
