OSSummit 2025 NA: The Power of Consolidation: A Unified Stack for Business Intelligence, Security, and Observability – Josh Lee, Altinity, Inc. & Mya Jaye, C8 Labs
Imagine you’re responding to a production incident, and you’re trying to answer simple questions about it. How many systems do you need to consult when assessing the impact of events at your company? Do you manage different technology stacks for observability, security, and business intelligence?
What if we told you, you could create a unified stack capable of serving all stakeholders simultaneously? In this talk, Mya and Josh explore how open source technologies like ClickHouse, OpenTelemetry, and Grafana enable complex business use cases using modern tooling and practices.
Regardless of your function, you will leave with a deeper understanding of how consolidating these concerns into a unified stack reduces technical complexity and provides a common language for everyone to use - from engineers building new features and product managers evaluating their success, to operators keeping the lights on and C suite’s birds-eye view of the company.
OSSummit 2025 NA: Panel Discussion: Build a Great Business on Open Source Without Selling Your Soul
A profitable business is one of the best protections for commercial open source projects and communities that depend on them.
This talk draws on the experience of companies that pulled it off to explain how to do it for your own projects. We’ll discuss commercial models that actually work, giving back to the community, and gracefully collecting money for free software.
We'll also touch on topics for larger projects like foundations and taking VC funding. It is possible to balance a strong belief in open source communities with making payroll every two weeks. We've done it and will share our secrets.

Altinity Event: Real-Time Data Lakes and ClickHouse® – Problems, Solutions, and The Road Ahead
Real-time databases are integrating with data lakes to reduce storage costs and share data with AI and data science. Please join us to hear longtime ClickHouse practitioners share current problems and solutions as they negotiate the transition from closed storage models to open table formats like Apache Iceberg. There will be plenty of time to network: discuss problems and brainstorm solutions with your peers.
Five Things Every New ClickHouse® User Should Know (Part 1: Applications)
ClickHouse runs like greased lightning because it's different.
How is it different?
Let us count the ways!
This talk introduces 5 important things you should understand to get your first application up and running fast. It includes how to set up ClickHouse, how to create tables, how to load data, how to run queries, and one more surprise topic that you won't expect. We'll focus on what makes ClickHouse different from any other database you've used and faster, too.
There will be plenty of time for questions, so bring it on.
Let's learn to build fast ClickHouse applications really fast!

KCDC 2025: What’s a Data Lake and What Does It Mean For My Open Source Stack?
Our CEO, Robert Hodges, is presenting the talk What’s a Data Lake and What Does It Mean For My Open Source Stack? at the Kansas City Developer Conference. The 2025 conference will be held August 13-15, with a pre-conference workshop day and two full conference days.
Data lakes on open table formats like Iceberg are a popular way to manage large datasets for analytics, data science, and AI. This talk explains how data lakes work and how to adapt open-source analytic stacks to use them. First, we'll tour projects like Arrow, Iceberg, and Unity Catalog that make data lakes possible. Next, we'll see how analytics engines like DuckDB, ClickHouse, and Spark are adapting. Finally, we'll survey a few projects that enable applications written in Python, Golang, or Rust to deliver fast queries. You'll have to build the app yourself, but this talk will show you a path to use data lakes and open source successfully.

Meetup PDXPUG: OSS Database Spotlight Clickhouse – Cheap, Fast, Scalable: Introducing Analytics with Open Source ClickHouse®
Our CEO, Robert Hodges, is presenting the talk Cheap, Fast, Scalable: Introducing Analytics with Open Source ClickHouse® at the PDXPUG: OSS Database Spotlight Clickhouse Meetup on September 4th.
Real-time analytic databases are indispensable tools for quick insights on large datasets, and ClickHouse currently leads the pack in speed and usage. This talk shows the major features that make ClickHouse popular for real-time analytics and provides a jumping-off point to build your own apps. We’ll explain the internals of ClickHouse and provide explicit guidance on when to reach for it. (And when not to.;) We will also demo new work from Altinity that adds separable compute and storage using shared Apache Iceberg tables. We’ll include thoughts on design patterns for using PostgreSQL and ClickHouse productively together.
