<h1>Step 3: Complete Delivery</h1>

<p>Santa&#39;s a busy robot, and all that ordnance is expensive. Once he&#39;s done
a delivery, he needs to mark it as done so he can move on to all the
other deserving people.</p>

<p>Stopping to check people off manually really slows down the murder and
mayhem.</p>

<p>Yancy makes it easy to update the data, this time with the <a href="https://metacpan.org/pod/Yancy::Controller::Yancy#set">&quot;set&quot; action

    $job->on( failed => sub( $job, $error ) {
        chomp $error;
        $logger->error( $error );
    });
});
</code></pre>

<p>To help us for future capacity planning, we want our workers to tell us if they are running at peak capacity, so log when this event occurs:</p>

<pre><code>$worker-&gt;on( busy =&gt; sub( $worker ) {
    my $max = $worker-&gt;status-&gt;{ jobs };
    $logger-&gt;log( &quot;$0: Running at capacity (performing $max jobs).&quot; );
});
</code></pre>

<p>Now, we apply the configuration (read below) to the worker. When the worker starts, it tells us information about how it was configured (this was really useful during development):</p>

<pre><code>my $max_jobs = $hostconfig-&gt;{ max_children };
my @queues   = @{ $hostconfig-&gt;{ queues }};
