Interface: LocalActivityOptions

common.LocalActivityOptions

Options for local activity invocation

Properties​

cancellationType​

• Optional cancellationType: ActivityCancellationType

Determines what the SDK does when the Activity is cancelled.

  • TRY_CANCEL - Initiate a cancellation request and immediately report cancellation to the workflow.
  • WAIT_CANCELLATION_COMPLETED - Wait for activity cancellation completion. Note that activity must heartbeat to receive a cancellation notification. This can block the cancellation for a long time if activity doesn't heartbeat or chooses to ignore the cancellation request.
  • ABANDON - Do not request cancellation of the activity and immediately report cancellation to the workflow.

localRetryThreshold​

• Optional localRetryThreshold: Duration

If the activity is retrying and backoff would exceed this value, a server side timer will be scheduled for the next attempt. Otherwise, backoff will happen internally in the SDK.

Default

1 minute

Format

number of milliseconds or ms-formatted string

retry​

• Optional retry: RetryPolicy

RetryPolicy that defines how an activity is retried in case of failure. If this is not set, then the SDK-defined default activity retry policy will be used. Note that local activities are always executed at least once, even if maximum attempts is set to 1 due to Workflow task retries.

scheduleToCloseTimeout​

• Optional scheduleToCloseTimeout: Duration

Indicates how long the caller is willing to wait for local activity completion. Limits how long retries will be attempted.

Either this option or startToCloseTimeout is required.

Default

unlimited

Format

number of milliseconds or ms-formatted string

scheduleToStartTimeout​

• Optional scheduleToStartTimeout: Duration

Limits time the local activity can idle internally before being executed. That can happen if the worker is currently at max concurrent local activity executions. This timeout is always non retryable as all a retry would achieve is to put it back into the same queue. Defaults to scheduleToCloseTimeout if not specified and that is set. Must be <= scheduleToCloseTimeout when set, otherwise, it will be clamped down.

Default

unlimited

Format

number of milliseconds or ms-formatted string

startToCloseTimeout​

• Optional startToCloseTimeout: Duration

Maximum time the local activity is allowed to execute after the task is dispatched. This timeout is always retryable.

Either this option or scheduleToCloseTimeout is required. If set, this must be <= scheduleToCloseTimeout, otherwise, it will be clamped down.

Format

number of milliseconds or ms-formatted string
