Request Header

Media Types: "application/json; odata=minimalmetadata"

Name Required Type Description
client-request-id

If-None-Match

string

An ETag value associated with the version of the resource known to the client. The operation will be performed only if the resource's current ETag on the service does not match the value specified by the client.

If-Modified-Since

string

date-time-rfc1123

A timestamp indicating the last modified time of the resource known to the client. The operation will be performed only if the resource on the service has been modified since the specified time.

If-Unmodified-Since

TaskConstraints

Execution constraints to apply to a Task.

Name Type Description
maxTaskRetryCount

integer

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).

maxWallClockTime

string

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.

retentionTime

string

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.

TaskUpdateParameter

The set of changes to be made to a Task.

Name Type Description
constraints

TaskConstraints

Constraints that apply to this Task.
If omitted, the Task is given the default constraints. For multi-instance Tasks, updating the retention time applies only to the primary Task and not subtasks.
