How to set a Start-To-Close Timeout in Java

To set a Start-To-Close Timeout, use ActivityOptions.newBuilder.setStartToCloseTimeout​.

This or ScheduleToClose must be set.

• Type: Duration
• Default: Defaults to ScheduleToCloseTimeout value

You can set Activity Options using an ActivityStub within a Workflow implementation, or per-Activity using WorkflowImplementationOptions within a Worker. Note that if you define options per-Activity Type options with WorkflowImplementationOptions.setActivityOptions(), setting them again specifically with ActivityStub in a Workflow will override this setting.

• With ActivityStub

  GreetingActivities activities = Workflow.newActivityStub(GreetingActivities.class,
              ActivityOptions.newBuilder()
                      .setStartToCloseTimeout(Duration.ofSeconds(2))
                      .build());

• With WorkflowImplementationOptions

  WorkflowImplementationOptions options =
              WorkflowImplementationOptions.newBuilder()
                      .setActivityOptions(
                              ImmutableMap.of(
                                "EmailCustomerGreeting",
                                      ActivityOptions.newBuilder()
                                            // Set Activity Execution timeout (single run)
                                            .setStartToCloseTimeout(Duration.ofSeconds(2))
                                            .build()))
                      .build();
