Temporal

Retry loops, recovery code and hand rolled state machines eat the time meant for the application. Temporal is a durable execution platform that takes that work over, without giving up scale or reliability.

The server executes units of application logic called Workflows in a resilient manner, handling intermittent failures and retrying failed operations on its own. It is a mature technology that began as a fork of Uber's Cadence, and it is developed by Temporal Technologies, a startup founded by the people who created Cadence.

Getting from install to a running workflow is a short path.

• Local server: one Homebrew install and one start command bring up a prebuilt image with its dependencies.
• Samples: Go and Java sample repositories run against the local server, from hello world upwards.
• CLI: the Temporal CLI lists namespaces and workflows and drives the running server.
• Web UI: a browser interface on port 8233 shows your sample workflows executing.
• Language support: Workflows, Activities and Workers are written in one of the supported SDK languages.

This repository holds the source of the server itself rather than the SDKs, and the server architecture is documented alongside the code. Proposals for new features have a repository of their own, and a community site handles questions from people getting started.
