Gleb enjoys outdoor traveling with his wife and two kids in a camper. **"One Does Not Simply Query a Stream"** Streaming data with Apache Kafka® has become the backbone of modern applications. While streams are ideal for continuous data flow, they lack built-in querying capabilities. Unlike databases with indexed lookups, Kafka’s append-only logs are designed for high-throughput processing—not for on-demand queries. This necessitates additional infrastructure to query streaming data effectively. Traditional approaches replicate stream data into external stores: relational databases like PostgreSQL for operational queries, object storage like S3 accessed via Flink, Spark, or Trino for analytics, and Elasticsearch for full-text search and log analytics. Each serves a purpose—but they also introduce silos, schema mismatches, freshness issues, and complex ETL pipelines that increase system fragility. In this session, we’ll explore solutions that aim to unify operational, analytical, and search workloads across real-time data. We'll demonstrate stream processing with Kafka Streams, Apache Flink®, and SQL engines; real-time analytics with Apache Pinot®; search capabilities with Elasticsearch; and modern lakehouse approaches using Apache Iceberg® with Tableflow to represent Kafka topics as queryable tables. While there's no one-size-fits-all solution, understanding the tools and trade-offs will help you design more robust and flexible architectures. **Viktor Gamov** is a Principal Developer Advocate at Confluent, founded by the original creators of Apache Kafka®.

Let's drink beers and shoot the shit about space! Plus, let's see some awesome astronomy content, delivered by our friends at [Astronomy On Tap](https://www.dunlap.utoronto.ca/public-outreach/astronomy-on-tap-to/). Let's meet at the [The Dog & Bear Pub](https://dogandbear.ca/), 1100 Queen St W, just a half block west from the Great Hall. We'll meet there at 6pm, do our traditional "drink beers and shoot the shit about space" (dinner also possible), and then head over to the AoT event starting 7:15 for entry by 7:30. Join us at any point, but DO expect that it'll be much harder to find us at the Great Hall than at any earlier point. We'll basically be pre-drinking at Dog & Bear, hoping to see double stars at Astronomy on Tap LOL. We will also bring one of our gliders for a bit of show & tell. More info on Astronomy On Tap: held every few months at the Great Hall by the Dunlap Institute, it's basically couple of astronomy lectures, usually by researchers, with a cash bar and tons of astronomy nerds. Doors at 7pm, show at 8pm, no cover and no tickets required, but in my experience it fills up so it's best to get there well before 8pm to get better seats.

They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience. Join us for a deep dive into the engineering reality of the OpenSearch stack, including: * **The Analysis:** Why the OpenSearch stack beat out the competition. * **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD. * **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale. * **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for. **If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**

This group is for anyone who wants to explore Buddhist meditation in a relaxed and supportive setting. Each session includes a short meditation, a simple teaching from Buddhist psychology, and an open discussion about how these ideas show up in everyday life. While our foundation is Buddhist practice, we love weaving in wisdom from other traditions whenever it helps us grow, find peace, and support each other. Members of our community come from many different backgrounds, and you do not need to consider yourself a Buddhist to attend. All are welcome. The session runs from 7:00 to 8:00 p.m., with doors open from 6:30 to 9:00. Come early or stay after if you’d like to enjoy some quiet reflection or casual conversation with the community. On the first Wednesday of each month, we share a potluck meal. Bring a dish if you’d like, but the most important thing you can bring is yourself. We look forward to seeing you!

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

**Schedule** 5:00 pm - 5:30 pm - Sign-in/Meet and greet/networking 5:30 pm - 7:00 pm - Break the Cloud Lock-in: Building Adaptive Intelligence Orchestration with DIO 7:00 pm - 7:45 pm - Leaning on the SQL: Crafting Resilient Data Layers **Talk and Speaker Details** **Time**: 5:30 pm est. **Title**: Break the Cloud Lock-in: Building Adaptive Intelligence Orchestration with DIO **Summary**: AIaas are often stuck in a binary choice: pay the "token tax" for convenient Cloud APIs or manage the complexity of local open-source models (Llama/Mistral) yourself. The future belongs to a hybrid architecture—but the routing logic shouldn't be spaghetti code. In this session, we introduce DIO (Distributed Intelligence Orchestration), a new open-source framework designed to bridge on-premise infrastructure and cloud capabilities. We will move beyond theory and look at the code behind the Federated Decision Engine (FDE)—the algorithm that allows you to dynamically route prompts based on privacy, cost, complexity, and more. **Session Takeaways:** \- The DIO Architecture: A technical deep dive into the open\-source framework that decouples your application from specific model providers\. \- Live Integration: How to implement the DIO SDK to build a "Smart Router" that connects the best of both world for Cloud & On Prem Intelligence\. **Speaker**: Snow Zhao **Speaker Bio**: Founder & CEO of AIgentic \| Ex\-Meta engineering leader\. Building the future of professional services with precision & trust\. Snow has decades of Silicon Valley experience building and scaling technology organizations at Facebook, Block (Cash App), and Groupon. She is currently building at AIgentic, an applied AI company designing robust, trustworthy AI systems for professional industries. She leads global teams that delivered secure, high-performance systems used by billions, from product infrastructure behind Messenger’s rewrite and end-to-end encryption, to architecting enterprise AI platforms that bridge traditional sectors with digital transformation. Her work has spanned mobile, security, open-source, federated architecture, AI-powered automation, cross-platform software ecosystems, and more — always guided by the principle that engineering excellence is a human discipline as much as a technical one. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Time**: 7:00 pm est. **Title**: Leaning on the SQL: Crafting Resilient Data Layers **Summary**: Most apps need to persist data. The mechanisms for persisting vary, from key-value pairs to relational databases to files and more. SQLite is the de-facto standard for persistence in mobile apps: it ships with every Android and iOS app. This session looks into best practices for SQLite data persistence, drawing from practical, digestible, real world examples. We look into when one should lean on the SQL versus when to perform data manipulation in application code. We look at some examples of constraints that you might have written in Kotlin/Swift, and how expressing them in SQL instead can offer data consistency and integrity benefits. A major focus of the session is on migrations. Data schemas inevitably evolve, and executing migrations carefully is essential, as mistakes can have severe consequences, including data corruption. We look into best practices for migration, including when to do migration in application code versus in SQL. We also examine some real world migration examples beyond the simple case of adding a column with a default value. Finally we look at migrations that cross data sources. This could occur if for example you were persisting data in a key-value store but you now want to migrate that to a database table. This must be done in application code but can you still take advantage of database migrations? Can you cover your migration code with unit tests? **Speaker**: Kiran Raon **Speaker Bio**: Two decades as a developer, got into Android in 2010. Adopted Kotlin in 2017, had my first attempt at KMP in 2019 (when it was still called KMM). Worked on and off with iOS and web client technologies throughout my career, also dabbled in other cross platform technologies.
