Highlights

Updates

• Instead of http://host:port, the target endpoint is now host:port to align with other SDKs (warns if scheme is present, will be an error next version).
• Support for activities as methods on instances instead of just top-level functions. Using an instance with, say a DB client as an instance property, is a good way to have it accessible from inside the activity. The @activity.defn decorator can be set on the method, and helpers like workflow.execute_activity_method are present to help typing/invocation.
• Support for activities as instances of classes with __call__ implemented. The @activity.defn decorator can be set on the class in that case, and helpers like workflow.execute_activity_class are present to help typing/invocation.
• Added many more fields to client.WorkflowExecutionDescription
• Several bug fixes

OpenTelemetry

An OpenTelemetry interceptor can now be provided that traces workflows and activities. Due to Temporal's replay capabilities where a workflow may start in one place and finish in another at a completely different time, the workflow tracing spans do not have durations, but they properly and deterministically represent the things done by a workflow. They are hierarchical and pass across servers so if, for example, an activity made an HTTP call, the HTTP span would appear in the activity span that would appear in the workflow span. See the README for more information.
