Class: DoBackoff
coresdk.activity_result.DoBackoff
Issued when a local activity needs to retry but also wants to back off more than would be reasonable to WFT heartbeat for. Lang is expected to schedule a timer for the duration and then start a local activity of the same type & same inputs with the provided attempt number after the timer has elapsed.
This exists because Core does not have a concept of starting commands by itself, they originate from lang. So expecting lang to start the timer / next pass of the activity fits more smoothly.
Properties
attempt
• attempt: number
The attempt number that lang should provide when scheduling the retry. If the LA failed on attempt 4 and we told lang to back off with a timer, this number will be 5.
backoffDuration
• Optional backoffDuration: null | $Properties
DoBackoff backoffDuration.
originalScheduleTime
• Optional originalScheduleTime: null | $Properties
The time the first attempt of this local activity was scheduled. Must be passed with attempt to the retry LA.
