The Retry component lets you repeatedly try to run a connected component until it succeeds (or a maximum number of attempts is reached). To attach the Retry component to another component, use the connection ring beneath the Retry component to connect to the input of the other component. The two components will automatically “snap” together, with the Retry component sitting on top of the other component, and can be dragged around the canvas as a single component. During the interval between retries, nothing is shown in the task panel, and it may appear that although the pipeline run hasn’t completed yet, nothing is running. Once the current wait time is reached, the task will be added to the run for its next attempt and the pipeline will continue.

​
Properties

​
Name
string
required
A human-readable name for the component.
​
Number of Retries
integer
required
The maximum number of attempts to retry the connected component. The total number of times the attached component could be run is one more than the number of retries. The original run is not a retry. If the final retry fails, the failure link is followed. The first time the component succeeds, the success link is followed.
​
Retry Delay
drop-down
required
Certain kinds of transient failures may benefit from a delay before retrying. The Retry Delay parameter provides strategies for retrying quickly or slowly, with the ability to leave longer and longer pauses between attempts (known as backoff).
  • Custom: Specify a custom delay value of hours, minutes, or seconds.
  • Long delay: Waits approximately 15 seconds between retries.
  • Long delay with backoff: Waits longer between each failure, at approximately 15, 30, 60, 120, 240… seconds.
  • Retry immediately: Will immediately retry up to the maximum number of retries. This is the default setting.
  • Short delay: Waits approximately 2 seconds between retries.
  • Short delay with backoff: Waits longer between each failure, at approximately 1, 2, 5, 10, 20, 40… seconds.
​
Retry Interval
integer
required
An integer value of the unit specified below. The default value is 1. An error will occur if the value is below 0 or above 3600. An error will also occur if the value is not an integer. Only available when Retry Delay is set to Custom.
​
Retry Time Unit
drop-down
required
Choose Hour, Minute, or Second. Only available when Retry Delay is set to Custom.
