Java ActivityOptions reference

Use ActivityOptions to configure how to invoke an Activity Execution.

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.

The following table lists all ActivityOptions that can be configured for an Activity invocation.

Option	Required	Type
setScheduleToCloseTimeout	Yes (if StartToCloseTimeout is not specified)	Duration
setScheduleToStartTimeout	No	Duration
setStartToCloseTimeout	Yes (if ScheduleToCloseTimeout is not specified)	Duration
setHeartbeatTimeout	No	Duration
setTaskQueue	No	String
setRetryOptions	No	RetryOptions
setCancellationType	No	ActivityCancellationType

ScheduleToCloseTimeout

To set a Schedule-To-Close Timeout, use ActivityOptions.newBuilder.setScheduleToCloseTimeout​.

This or StartToCloseTimeout must be set.

• Type: Duration
• Default: Unlimited. Note that if WorkflowRunTimeout and/or WorkflowExecutionTimeout are defined in the Workflow, all Activity retries will stop when either or both of these timeouts are reached.

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()
                          .setScheduleToCloseTimeout(Duration.ofSeconds(5))
                          .build());

• With WorkflowImplementationOptions

  WorkflowImplementationOptions options =
              WorkflowImplementationOptions.newBuilder()
                      .setActivityOptions(
                              ImmutableMap.of(
                                      "GetCustomerGreeting",
                                      ActivityOptions.newBuilder()
                                          .setScheduleToCloseTimeout(Duration.ofSeconds(5))
                                          .build()))
                      .build();

ScheduleToStartTimeout

To set a Schedule-To-Start Timeout, use ActivityOptions.newBuilder.setScheduleToStartTimeout​.

• Type: Duration
• Default: Unlimited. This timeout is non-retryable.

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()
                          .setScheduleToStartTimeout(Duration.ofSeconds(5))
                          // note that either StartToCloseTimeout or ScheduleToCloseTimeout are
                          // required when setting Activity options.
                          .setScheduletoCloseTimeout(Duration.ofSeconds(20))
                          .build());

                      .build();

StartToCloseTimeout

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.
