Properties of a PollActivityTaskQueueResponse.

Properties​

activityId?​

optional activityId?: string | null

The autogenerated or user specified identifier of this activity. Can be used to complete the activity via RespondActivityTaskCompletedById. May be re-used as long as the last usage has resolved, but unique IDs for every activity invocation is a good idea. Note that only a workflow activity ID may be autogenerated.

activityRunId?​

optional activityRunId?: string | null

The run ID of the activity execution, only set for standalone activities.

activityType?​

optional activityType?: $Properties | null

PollActivityTaskQueueResponse activityType

attempt?​

optional attempt?: number | null

Starting at 1, the number of attempts to perform this activity

currentAttemptScheduledTime?​

optional currentAttemptScheduledTime?: $Properties | null

When was this task attempt scheduled

optional header?: $Properties | null

Headers specified by the scheduling workflow. Commonly used to propagate contextual info from the workflow to its activities. For example, tracing contexts.

pollerGroupInfos?​

optional pollerGroupInfos?: $Properties[] | null

The weighted list of poller groups IDs that client should use for future polls to this task queue. Client is expected to:

  1. Maintain minimum number of pollers no less than the number of groups.
  2. Try to assign the next poll to a group without any pending polls,
  3. If every group has some pending polls, assign the next poll to a group randomly according to the weights.

pollerGroupsInfo?​

optional pollerGroupsInfo?: $Properties | null

The weighted, versioned list of poller groups IDs that client should use for future polls to this task queue. Client should ignore this if it has already applied a snapshot with a version greater than or equal to poller_groups_info.version. Client is expected to:

  1. Maintain minimum number of pollers no less than the number of groups.
  2. Try to assign the next poll to a group without any pending polls,
  3. If every group has some pending polls, assign the next poll to a group randomly according to the weights.
