<p>I have a metric counter that records during the execution of multiple webhooks.<br />
Do we need to implement locking when incrementing the metric counter to prevent race conditions?</p>
<p>Apart from this, does the admission controller support handling multiple admission requests simultaneously? For example, if there are 2 admission requests, will the admission controller execute one after another, or simultaneously?</p>

<p>A short answer is that the requests are an API call behind the scenes and are executed <strong>simultaneously</strong>.</p>
<h3>A bit longer answer will be:</h3>
<ul>
<li>The requests are API calls.</li>
<li>Behind the scenes, there are &quot;hooks&quot; that intercept the requests and execute them.</li>
<li>The above request can generate latency in some cases when there is a problem and they are not processes, then can even throw a timeout.</li>
<li>The requests can be divided into &quot;buckets&quot; per namespace.</li>
<li>You can limit the number of requests per namespace</li>
<li>You can limit by a specific user</li>
</ul>
