<dt>Field Reference</dt>
<dd>
<ul>
<li>
<span class="param">Diff</span>
A diff structure between the submitted job and the server side version.
The top-level object is a Job Diff which contains Task Group Diffs,
which in turn contain Task Diffs. Each of these objects then has Object
and Field Diff structures embedded.
</li>
<li>
<span class="param">NextPeriodicLaunch</span>
If the job being planned is periodic, this field will include the next
launch time for the job.
</li>
<li>
<span class="param">CreatedEvals</span>
A set of evaluations that were created as a result of the dry-run. These
evaluations can signify a follow-up rolling update evaluation or a
blocked evaluation.
</li>
<li>
<span class="param">JobModifyIndex</span>
The JobModifyIndex of the server side version of this job.
</li>
<li>
<span class="param">FailedTGAllocs</span>
A set of metrics to understand any allocation failures that occurred for
the Task Group.
</li>
<li>
<span class="param">Annotations</span>
Annotations include the DesiredTGUpdates, which tracks what the
scheduler would do given enough resources for each Task Group.
</li>
</ul>
</dd>
</dl>
<dl>
<dt>Description</dt>
<dd>
Forces a new instance of the periodic job. A new instance will be created
even if it violates the job's
[`prohibit_overlap`](/docs/job-specification/periodic.html#prohibit_overlap) settings. As
such, this should be only used to immediately run a periodic job.
