v1.27.0

💥 BREAKING CHANGES

Update With Start (Pre-release)

WorkflowClient

• WorkflowClient.updateWithStart has been renamed to WorkflowClient.startUpdateWithStart.
• Instead of taking the workflow method, workflow arguments and a UpdateWithStartWorkflowOperation, WorkflowClient.startUpdateWithStart now takes the update method, update arguments and a WithStartWorkflowOperation. WithStartWorkflowOperation contains the workflow method and workflow arguments to be executed together with the update request.

WorkflowStub

• WorkflowStub.updateWithStart has been renamed to WorkflowStub.startUpdateWithStart.
• WorkflowStub.startUpdateWithStart now just takes the UpdateOptions, update arguments and workflow arguments.

Update (Public Preview)

• The SDK now preforms more rigorous type validation when registering a Workflow with an @UpdateValidatorMethod to make sure the type parameters match the linked @UpdateMethod.
• The SDK will no longer sometimes throw WorkflowUpdateException when calling WorkflowStub.startUpdate if the update is rejected. WorkflowUpdateException is now consistently throw when getting the result of the update
• UpdateOptionsBuilder no longer generates a update ID when built. Now a unique UUID is generated when the options are used. This is similar to how WorkflowOptions and workflow ID work.

Nexus (Private Preview)

• Workflow started by a Nexus operation now require the Workflow ID to be specified in the WorkflowOptions.
• The SDK now preforms more rigorous type validation when registering a Nexus Service to make sure it implements the service properly.
• All header maps for Nexus operations are now properly case-insensitive.
• Nexus on Temporal is now in Public Preview.

Highlights

Virtual Threads (Public Preview)

The Java SDK now has experimental support for virtual threads when using a JVM with a version of 21 or higher. Virtual threads can be used inside workflows by enabling WorkerFactoryOptions.setUsingVirtualWorkflowThreads. Users can also use virtual threads for task processing in a worker by enabling WorkerOptions.setUsingVirtualThreads.

Nexus (Private Preview)

WorkerInterceptor now has support for intercepting Nexus workers.

Update (Public Preview)

WorkflowClient now has a set of static methods called startUpdate that can be used to start an update, but not immediately wait on the result. This is a type safe analog to WorkflowStub.startUpdate.

Workflow Metadata (Public Preview)

• The Java SDK now exposes a fixed summary option for local and normal activities.
• The Java SDK now support __temporal_workflow_metadata query, this query allows users to get details about a workflow like its’ current description and what signal, update, and query handlers are registered.
