TimescaleDB Course – PostgreSQL for Time-Series Data

<p>Managing massive, rapidly growing datasets efficiently is a critical skill for modern developers. Whether you are tracking API request logs, monitoring IoT fleet telemetry, or building dashboards for AI agents, unoptimized time-series data can quickly slow standard PostgreSQL queries to a crawl. We just posted a new course on the freeCodeCamp.org YouTube channel that will teach you all about TimescaleDB</p> <p>You'll get hands-on experience with TimescaleDB in this course, discovering how to upgrade PostgreSQL into an optimized time-series database. You will learn to optimize query speeds, drastically reduce storage footprints, and ensure your dashboards stay fast at scale.</p> <p>Key concepts and hands-on projects include:</p> <ul> <li><p><strong>Hypertables &amp; Chunk Management</strong><br>Learn how TimescaleDB automatically partitions your data by time to speed up queries and streamline data retention without painful row deletions.</p> </li> <li><p><strong>Columnar Storage &amp; Compression</strong><br>Discover how converting older row data into column-oriented batches can shrink your database size by over 90% and massively speed up analytical queries.</p> </li> <li><p><strong>Continuous Aggregates</strong><br>Stop recalculating identical data! You'll build incremental, automatically updating materialized views (and aggregate "ladders") that keep dashboards returning results in milliseconds.</p> </li> <li><p><strong>Hyperfunctions &amp; Gap Filling</strong><br>Master specialized time-series functions for calculating percentiles, distinct counts, handling counter resets, and smoothing out data gaps for clean frontend charting.</p> </li> <li><p><strong>Data Tiering &amp; Vector Search</strong><br>Explore moving older, cold data out of expensive local SSDs into cheaper S3 object storage seamlessly, and see how to combine standard time-series queries with AI vector search.</p> </li> </ul> <p>The course walks you through building two complete, production-ready projects from scratch:</p> <ol> <li><p><strong>An AI Agent Flight Recorder</strong><br>Track millions of language model inferences, tool calls, costs, and latencies locally in Docker.</p> </li> <li><p><strong>An EV Charger Fleet Telemetry System</strong><br>Monitor 2,000 devices reporting every 10 seconds, deployed directly on the fully-managed Tiger Cloud platform.</p> </li> </ol> <p><a href="https://youtu.be/gYTA8nQN030?utm_source=gemini"><strong>Watch the full TimescaleDB Course on the freeCodeCamp.org YouTube channel</strong></a> <strong>(4-hour watch).</strong></p> <div class="embed-wrapper"><iframe width="560" height="315" src="https://www.youtube.com/embed/gYTA8nQN030" style="aspect-ratio: 16 / 9; width: 100%; height: auto;" title="YouTube video player" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen="" loading="lazy"></iframe></div>
