Durable execution for PHP, Python, and Rust.

Durable Workflow keeps long-running application code moving through process restarts, retries, timers, and human input. Workflows and activities are written in ordinary application code while the runtime records history and resumes work without repeating completed steps.

The SDKs share workflow and activity type names, task queues, namespaces, and a portable Avro value protocol. A workflow in one language can dispatch an activity to a worker in another.

• Durable workflows and activities with retries, timeouts, and heartbeats
• Timers, schedules, signals, queries, and updates
• Child workflows, sagas, cancellation, and continue-as-new
• Namespaces, search attributes, memo, and workflow history
• Waterline for operational visibility and control
• dw for command-line operation

Durable Workflow is created and maintained by Richard McDaniel (@rmcdaniel), who is also responsible for security maintenance, vulnerability triage, and security fixes across the project.
