The other requests don&rsquo;t queue up behind the first and repeat it. They attach to it.</p> <p>It sounds like a cache, and it&rsquo;s related, but it works at a different moment. A cache helps after the answer exists. Coalescing helps while the answer is still being made, which is exactly when duplicates hurt most: a slow report, an expensive API call, a page that a thousand visitors hit the second it expires from the cache.</p>
