BatchTaskConstraints Class
Execution constraints to apply to a Task.
Constructor
BatchTaskConstraints(*args: Any, **kwargs: Any)Variables
| Name | Description |
|---|---|
|
max_wall_clock_time
|
The maximum elapsed time that the Task may run, measured from the time the Task starts. If the Task does not complete within the time limit, the Batch service terminates it. If this is not specified, there is no time limit on how long the Task may run. The time duration is specified in ISO 8601 format. |
|
retention_time
|
The minimum time to retain the Task directory on the Compute Node where it ran, from the time it completes execution. After this time, the Batch service may delete the Task directory and all its contents. The default is 7 days, i.e. the Task directory will be retained for 7 days unless the Compute Node is removed or the Job is deleted. The time duration is specified in ISO 8601 format. |
|
max_task_retry_count
|
The maximum number of times the Task may be retried. The Batch service retries a Task if its exit code is nonzero. Note that this value specifically controls the number of retries for the Task executable due to a nonzero exit code. The Batch service will try the Task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries the Task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry the Task after the first attempt. If the maximum retry count is -1, the Batch service retries the Task without limit, however this is not recommended for a start task or any task. The default value is 0 (no retries). |
Methods

Return a dict that can be turned into json using json.dump. |
| clear |
Remove all items from D. |
| copy | |
| get |
Get the value for key if key is in the dictionary, else default. :param str key: The key to look up. :param any default: The value to return if key is not in the dictionary. Defaults to None :returns: D[k] if k in D, else d. :rtype: any |

Attributes
max_task_retry_count
The maximum number of times the Task may be retried. The Batch service retries a Task if its exit code is nonzero. Note that this value specifically controls the number of retries for the Task executable due to a nonzero exit code. The Batch service will try the Task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries the Task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry the Task after the first attempt. If the maximum retry count is -1, the Batch service retries the Task without limit, however this is not recommended for a start task or any task. The default value is 0 (no retries).
max_task_retry_count: int | Nonemax_wall_clock_time
The maximum elapsed time that the Task may run, measured from the time the Task starts. If the Task does not complete within the time limit, the Batch service terminates it. If this is not specified, there is no time limit on how long the Task may run. The time duration is specified in ISO 8601 format.
max_wall_clock_time: timedelta | Noneretention_time
The minimum time to retain the Task directory on the Compute Node where it ran, from the time it completes execution. After this time, the Batch service may delete the Task directory and all its contents. The default is 7 days, i.e. the Task directory will be retained for 7 days unless the Compute Node is removed or the Job is deleted. The time duration is specified in ISO 8601 format.
