Then I hit 200 concurrent requests, and it failed epically.</p> <p>The CPU spiked to full usage because of pydub&rsquo;s processing. The TTS API didn&rsquo;t rate-limit me but, it was horribly slow. Then the jobs started failing. Half the jobs died silently. The other half wrote corrupted files because of race conditions I didn&rsquo;t know existed. And when I deployed a little fix? The deployment killed in-flight jobs, leaving orphaned audio segments scattered across cloud storage directory.</p>
