Our Community Champions and Creators are doing some amazing work.

Community Champion and Sāo Paulo MUG Leader @Leandro_Domingues led a session about Relational Migrator in SQL in Brazil.

Our MongoDB Community Forum has always been a great place for questions and discussions related to learning, using, developing, or otherwise working with MongoDB products, services, and ecosystems. Connect with MongoDB community members and employees who can guide you along the way!

We’d like to acknowledge some exceptional contributors. Big congrats to Community Champions @chris and @michael_hoeller and Community Creators Vishal and @Fabio_Ramohitaj for achieving the Forum Elder badge, our highest community recognition. Lastly, great work by @Yilmaz_Durmaz, @Doug_Duncan, @Mahi_Satyanarayana, @Prasad_Saya, and @steevej.

These experts play a vital role in fostering our community’s growth.

You might be familiar with our MUGs, that’s MongoDB User Groups. Locals meet up all over the world to discuss the magic of MongoDB and tech as a whole.

We recently met up in Sao Paolo, organized by our experienced MUG Leader & Community Creator Rodrigo and MUG Leader & Community Champion Leandro.

MongoDB’s Lourenço enlightened the audience with a session on the Relational Migrator. Additionally, MUG Leader & Community Champion Leandro provided insights into the latest features of MongoDB 7.0, complemented by a practical demonstration of the aggregation framework.

We held a MUG in Belgium in partnership with Data Meetup Antwerp. Amazing work by @Sander_De_Vos in organizing the eventing and also doing a deep dive into MongoDB’s developer data platform and what’s new in MongoDB 7.0.

Wan, Markus, and the rest of the team in Sydney organized another amazing MUG. They had two sessions. Brad, Head of Product and Engineering at Konvoy Kegs, presented “Effervescent Efficiency: IoT Solutions for Breweries and Beyond,” focusing on IoT-enabled beverage logistics.

It focused on how MongoDB helps with IoT solutions for the beverage industry. For the second session, Avinash introduced “Advancing Data Visualization with Atlas Charts,” emphasizing the power of data visualization tools for MongoDB data.

There’s more! Our Beijing MUG Leaders Li Dan and Nora organized the first Beijing MUG in partnership with several open-source communities including Apache Dorris, Alibaba Cloud OSS, and Tapdata. This event centered around the trending theme of the “Modern Data Stack,” providing in-depth discussions on the performance and advantages of various tools within the modern data stack ecosystem.

Back in the US, Cassiano organized a MUG in Chicago in the last week of September. He covered the hot topics of unveiling MongoDB’s Data Modeling and Schema Design as well as what’s new in MongoDB, which included live demonstrations showcasing the capabilities of semantic search and AI-powered applications.

We also had Jacob from Proofpoint, who dove into exploring detection-as-code with MongoDB Change Streams. Additionally, he elaborated on how MongoDB and detection-as-code practices can drive security detections in your environment with a proof-of-concept implementation.


Our MUG Leader and Community Creator Sumanta organized a MUG in Kolkata where he and our speakers (Avinandan and Soumyadip) talked about how MongoDB seamlessly integrates with AWS to achieve scalable, efficient, and robust solutions. The session further delved into augmented reality and supercharging MongoDB using React server components.

I bet you thought I was done. One more! This month, we had a MUG in San Francisco. Organized by MUG Leader Gyanesh, this MUG featured a talk by Tom about the history of MongoDB and the Relational Migrator, as well as an impressive overview of Atlas Vector Search with MongoDB Developer Advocate Hubert. We also saw two of our attendees — Francis and Fernando — share their experiences on LinkedIn.
