Complete this [CFP form](https://clickhou.se/chmeetup-cfp) and we’ll be in touch.** **_____________________________________** **🎤 Session Details: The Journey to Zero-Copy: How chDB Became the Fastest SQL Engine on Pandas DataFrame** In this talk, Auxten Wang, creator and lead developer of chDB, shares the story of how the world’s fastest OLAP engine was made to fly on Pandas DataFrames, reducing query times from 30 seconds to just 0.5 seconds. He walks through chDB’s evolution from a serialization-bound prototype into a fully zero-copy SQL engine for Pandas, covering how DataFrame and Parquet round-trips were eliminated, how Python GIL limitations were overcome, and how string handling was rethought for parallel performance. The result is true DataFrame in and DataFrame out SQL with ClickHouse speed, delivering up to 200× faster analytics, native JSON support, streaming for data larger than RAM, and a complete zero copy loop with no servers, no setup, and no friction. **Speaker: Auxten Wang, Technical Director @ ClickHouse** Auxten Wang is a Technical Director at ClickHouse with 15 years of experience designing high-performance databases, recommender of systems, and infrastructure across startups and major tech firms. He co-founded CovenantSQL and contributed storage-layer and write-query functionality to a decentralized SQL database with blockchain features, and is an active author/contributor to ClickHouse and low-level projects like jemalloc, Kubernetes, and Memcached. His background includes leading RecSys and infrastructure teams as Principal Engineer at Shopee and director-level roles at 4Paradigm, combining production ML/recsys experience with rigorous systems engineering. Early at Baidu he architected and implemented Gingko—the company’s p2p large-dataset distribution system—writing the majority of its C++ code and applying a Dynamo-inspired design. Based in Singapore, he brings a rare mix of hands-on C/C++ systems work, testing and storage engineering, and product-driven startup leadership. **🎤 Session Details: Powering Bullet's Sub-millisecond Perpetuals Trading Platform** Tristan Frizza, Co-Founder and CTO of Sierra Research, shares their multi-year journey to delivering low latency and near real time trading data, charts, leaderboards, and analytics at scale. This talk explores the evolution from data lakes and complex, painful serving architectures to a streamlined single source of truth powered by ClickHouse Cloud, highlighting the technical lessons learned in building fast, reliable analytics for demanding trading workloads. **Speaker: Tristan Frizza, Co-Founder and CTO @ Sierra Research** Tristan Frizza is the Co-Founder and CTO of Sierra Research, focused on building the financial infrastructure the world deserves. Originally from Australia and now based in Singapore, he has led the development of high-performance trading and consumer systems, including a decentralized trading platform with over 100,000 users and $15B in notional volume. Previously, Tristan worked in machine learning and data science roles at Atlassian, Nearmap, and Lumaway, to name a few, building large-scale ML systems and data infrastructure used by tens of millions of users.

Over at the extension, we will visit the Exhibition @ Forest Discovery Centre to see the works of students from LASALLE College of the Arts. The exhibition, ‘Tending to the Garden’ is motivated by the human tendency to record not only to hold on to individual memories, but to open new pathways for care to emerge. Five artists 🧑‍🎨 from LASALLE contemplate how their desires & perspectives affect the archives they choose to keep. We will explore the vicinity before heading for lunch (optional) at Adam Road Food Centre.

This is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance. Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology Life Improvement Center of Central Ohio.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
