  • Method Details

    • setScheduleToCloseTimeout

      public ActivityOptions.Builder setScheduleToCloseTimeout(Duration scheduleToCloseTimeout)
      Total time that a workflow is willing to wait for an Activity to complete.

      ScheduleToCloseTimeout limits the total time of an Activity's execution including retries (use setStartToCloseTimeout(Duration) to limit the time of a single attempt).

      Either this option or setStartToCloseTimeout(Duration) is required.

      Defaults to unlimited, which is chosen if set to null.

    • setScheduleToStartTimeout

      public ActivityOptions.Builder setScheduleToStartTimeout(Duration scheduleToStartTimeout)
      Time that the Activity Task can stay in the Task Queue before it is picked up by a Worker.

      ScheduleToStartTimeout is always non-retryable. Retrying after this timeout doesn't make sense as it would just put the Activity Task back into the same Task Queue.

      Defaults to unlimited.

    • setStartToCloseTimeout

      public ActivityOptions.Builder setStartToCloseTimeout(Duration startToCloseTimeout)
      Maximum time of a single Activity attempt.

      Note that the Temporal Server doesn't detect Worker process failures directly. It relies on this timeout to detect that an Activity that didn't complete on time. So this timeout should be as short as the longest possible execution of the Activity body. Potentially long-running Activities must specify HeartbeatTimeout and call ActivityExecutionContext.heartbeat(Object) periodically for timely failure detection.

      If setScheduleToCloseTimeout(Duration) is not provided, then this timeout is required.

    • setHeartbeatTimeout

      public ActivityOptions.Builder setHeartbeatTimeout(Duration heartbeatTimeoutSeconds)
      Heartbeat interval. Activity must call ActivityExecutionContext.heartbeat(Object) before this interval passes after the last heartbeat or the Activity starts.

    • setTaskQueue

      public ActivityOptions.Builder setTaskQueue(String taskQueue)
      Task queue to use when dispatching activity task to a worker. By default, it is the same task list name the workflow was started with. Default is used if set to null.

    • setRetryOptions

      public ActivityOptions.Builder setRetryOptions(RetryOptions retryOptions)
      RetryOptions that define how an Activity is retried in case of failure.

      If not provided, the server-defined default activity retry policy will be used. If not overridden, the server default activity retry policy is: 

      
   InitialInterval:         1 second
   BackoffCoefficient:      2
   MaximumInterval:         100 seconds   // 100 * InitialInterval
   MaximumAttempts:         0             // Unlimited
   NonRetryableErrorTypes:  []

      If both setScheduleToCloseTimeout(Duration) and RetryOptions.Builder.setMaximumAttempts(int) are not set, the Activity will not be retried.

      To ensure zero retries, set RetryOptions.Builder.setMaximumAttempts(int) to 1.

    • setContextPropagators

      public ActivityOptions.Builder setContextPropagators(List<ContextPropagator> contextPropagators)
      Note:
      This method has extremely limited usage. The majority of users should just set WorkflowClientOptions.getContextPropagators()

      Both "client" (workflow worker) and "server" (activity worker) sides of context propagation from a workflow to an activity exist in a worker process (potentially the same one), so they typically share the same worker options. Specifically, ContextPropagators specified on WorkflowClientOptions.getContextPropagators(). WorkflowClientOptions.Builder.setContextPropagators(List) is the right place to specify ContextPropagators between Workflow and an Activity.
      Specifying context propagators with this method overrides them only on the "client" (workflow) side and can't be automatically promoted to the "server" (activity worker), which always uses ContextPropagators from WorkflowClientOptions.getContextPropagators()
      The only legitimate usecase for this method is probably a situation when the specific activity is implemented in a different language and in a completely different worker codebase and in that case setting a ContextPropagator that is applied only on a "client" side could make sense.
      This is also why there is no equivalent method on LocalActivityOptions.

      Parameters:
      contextPropagators - specifies the list of context propagators to use during propagation from a workflow to the activity with these ActivityOptions. This list overrides the list specified on WorkflowClientOptions.getContextPropagators(), null means no overriding

    • setCancellationType

      public ActivityOptions.Builder setCancellationType(ActivityCancellationType cancellationType)
      In case of an activity's scope cancellation the corresponding activity stub call fails with a CanceledFailure.
      Parameters:
      cancellationType - Defines the activity's stub cancellation mode. The default value is ActivityCancellationType.TRY_CANCEL

    • setDisableEagerExecution

      public ActivityOptions.Builder setDisableEagerExecution(boolean disableEagerExecution)
      If set to true, will not request eager execution regardless of worker settings. If false, eager execution may still be disabled at the worker level or eager execution may not be requested due to lack of available slots.

      Eager activity execution means the server returns requested eager activities directly from the workflow task back to this worker which is faster than non-eager which may be dispatched to a separate worker.

      Defaults to false, meaning that eager activity execution will be requested if possible.

    • setVersioningIntent

      @Deprecated public ActivityOptions.Builder setVersioningIntent(VersioningIntent versioningIntent)
      Deprecated.
      Use Worker Deployments
      Specifies whether this activity should run on a worker with a compatible Build Id or not. See the variants of VersioningIntent.

    • setSummary

      @Experimental public ActivityOptions.Builder setSummary(String summary)
      Single-line fixed summary for this activity that will appear in UI/CLI. This can be in single-line Temporal Markdown format.

      Default is none/empty.

    • setPriority

      @Experimental public ActivityOptions.Builder setPriority(Priority priority)
      Optional priority settings that control relative ordering of task processing when tasks are backed up in a queue.

      Defaults to inheriting priority from the workflow that scheduled the activity.

    • mergeActivityOptions

      public ActivityOptions.Builder mergeActivityOptions(ActivityOptions override)

    • mergeMethodRetry

      public ActivityOptions.Builder mergeMethodRetry(MethodRetry r)
      Properties that are set on this builder take precedence over ones found in the annotation.
