+
+## Concept of the episode: PopSQL
+
+It may be familiar to some of our viewers to describe an environment where
+key queries and dashboards are buried in someone's personal workspace, and you
+have to go ask them directly every time you want to check on your metrics.
+When you're running a world-class, highly-performant query engine like Trino and
+investing time and resources into maintaining it, shouldn't you treat your
+queries like a first-class, collaborative, versioned system, too?
+
+[PopSQL](https://popsql.com/), a playful spin on the word popsicle, solves the
+sadness that is disorganized and siloed insights by centralizing queries into a
+platform that has versioning, security, and a suite of collaborative tools
+comparable to Google Drive. Want to work with your teammate on a query? You can
+open up the same editor and see the same thing. Want to see what that query
+someone ran last week was to see how the new feature is doing? It's there. Have
+a suggestion to improve something? Leave a comment. Realize your suggestion was
+wrong and need to undo the change? You can view past versions of the query.
+
+PopSQL and Trino make sense together. PopSQL provides a best-in-class interface
+for organizing, collaborating, and working together on all of your SQL queries
+across the business, and Trino handles running those queries at unparalleled
+speeds. They go hand-in-hand for treating your data and SQL analytics as first
+class citizens. In today's episode, we'll be exploring what PopSQL is, how it
+integrates with Trino, and how the engineers at PopSQL have done some cool
+things with Trino to make the integration better than ever before. We'll start
+with that last one, actually.
+
+## Concept of the episode: A new Node.js adapter for Trino
+
+Trino in the frontend is... a tricky thing. We can go ahead and admit that the
+[Trino web UI](/docs/current/admin/web-interface.html) isn't going to win any
+awards for design or functionality. And while a couple Node-based libraries
+exist out there, including [presto-client-node](https://www.npmjs.com/package/presto-client)
+and [lento](https://github.com/vweevers/lento). But presto-client-node lacked
+support for streaming and had some issues handling 500 errors, and lento doesn't
+quite support Trino out of the box and only supports single streams, which
+wasn't ideal for PopSQL's distributed architecture. So when PopSQl's engineers
+went to build their frontend and integrate with Trino, what did they do? Build
+their own adapter.
+
+We'll talk about how it was implemented, what key features it unlocks, and why
+it makes using PopSQL with Trino an even better experience.
+
+## Demo of the episode: Using PopSQL with Trino
+
+It's hard to write show notes for a demo, because you can't really experience
+the demo by reading about what's happening. But as a surface-level overview,
+we'll be going over:
+
+* Setting up a connection
+* The schema explorer
+* The SQL editor
+* Query scheduling
+
+## PR of the episode: #57 on trino-gateway: Release version 3
+
+Last week, the community officially released the
+[trino-gateway](https://github.com/trinodb/trino-gateway), a proxy and load
+balancer that enables large operations to run multiple Trino clusters in
+harmony with each other to serve big queries and small queries alike. If you or
+your organization have a need for more than one Trino cluster and want the
+seamless experience of being able to connect to any of them through a single
+interface, then check it out! It's the product of many months of effort and
+should be a fantastic solution for running Trino at the absolute largest scales.
+
+To learn more about it, you should check out

+
+## Rounding out
+
+Trino Summit, the biggest Trino event of the year, is coming up on the 13th and
+14th of December, and like Trino Fest, it'll be fully virtual. If you'd like to
+give a talk about anything related to Trino, we're looking for speakers now.
+[Submit your talk here!](https://sessionize.com/trino-summit-2023/) If you'd
+rather attend, you can also
+[go register to attend now](https://www.starburst.io/info/trinosummit2023/?utm_source=trino&utm_medium=website&utm_campaign=NORAM-FY24-Q4-EV-Trino-Summit-2023&utm_content=tcb).
+
+Prior to Trino Summit, if you'd like to learn about SQL from the absolute
+experts, we've also announced the [Trino Training Series](/blog/2023/09/27/training-series)
+that we'll be running as a buildup to the summit. Register now and look forward
+to four great sessions starting from the ground up and ending with some key
+tricks and Trino specifics that even a seasoned SQL veteran may not know about.
+
+If you want to learn more about Trino, get the definitive guide from
+O'Reilly. You can download
+[the free PDF](https://www.starburst.io/info/oreilly-trino-guide/) or
+buy the book online.
