State of Open Con® 25 London: Data Sovereignty in Observability
As OpenTelemetry rapidly becomes the standard for open-source observability instrumentation, the question of data sovereignty takes center stage. In this panel, Josh Lee moderates a lively discussion with Hazel Weakly, Robert Hodges, and Edith Puclla—leaders in the fields of observability, databases, and open source. Together, they will explore the implications of data sovereignty in observability, balancing control, and compliance with innovation. Topics will include the role of open-source tools, the challenges of ensuring data portability, and the future of observability architectures in a sovereignty-conscious world.
Distributed Tracing with ClickHouse® & OpenTelemetry
Have you ever wondered what happens inside a distributed database when you run a query? In this webinar, we’ll explore the inner workings of ClickHouse using OpenTelemetry-compatible distributed tracing.
First, we’ll analyze the internal workings of various ClickHouse clusters while we run a variety of queries.
Then we’ll show how to use OpenTelemetry- and eBPF-based tools to observe queries coming into ClickHouse with context from the client applications, creating comprehensive end-to-end traces.
Finally, we’ll show how ClickHouse itself can be used as a versatile storage layer for trace data, and we’ll connect our data in ClickHouse to trace to visualization tools like Jaeger and Grafana.

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.
Our 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 discuss 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.

SCaLE X 2025 – Boosting MySQL with Vector Search: Introducing the MyVector Plugin
As the demand for vector databases and Generative AI continues to rise, integrating vector storage and search capabilities into traditional databases has become increasingly important. This session introduces the *MyVector Plugin*, a project that brings native vector storage and similarity search to MySQL. Unlike PostgreSQL, which offers interfaces for adding new data types and index methods, MySQL lacks such extensibility. However, by utilizing MySQL's server component plugin and UDF, the *MyVector Plugin* successfully adds a fully functional vector search feature within the existing MySQL + InnoDB infrastructure, eliminating the need for a separate vector database. The session explains the technical aspects of integrating vector support into MySQL, the challenges posed by its architecture, and real-world use cases that showcase the advantages of combining vector search with MySQL's robust features. Attendees will leave with practical insights on how to add vector search capabilities to their MySQL systems.
FOSSASIA SUMMIT 2025 – Unified Observability: Leveraging ClickHouse as a Comprehensive Telemetry Database
As modern infrastructures become more complex, traditional monitoring tools often struggle to provide a complete understanding of system health. This presentation will explore how ClickHouse, a high-performance columnar database, enables unified observability by consolidating metrics, logs, traces, and eBPF data into a scalable platform.
Attendees will learn how fragmented telemetry systems can hinder root-cause analysis and operational efficiency and how ClickHouse overcomes these challenges by offering seamless integration with tools like OpenTelemetry, Grafana, Prometheus, and more. We will also compare observability solutions, such as Coroot, qryn, and custom stacks with Jaeger and Loki, to demonstrate how ClickHouse simplifies data management, enhances real-time analysis, and supports large-scale telemetry use cases.
This session will provide practical insights into implementing ClickHouse for observability, enabling engineers to focus on system insights while minimizing infrastructure complexity.

ClickHouse® Disaster Recovery: Tips and Tricks to Avoid Trouble in Paradise
ClickHouse usually works like a charm, but what if a real disaster strikes?
This webinar introduces popular ways to protect your ClickHouse cluster and maybe your job, too.
Our talk starts with the main patterns for setting up ClickHouse disaster recovery and shows available techniques like cross-region replication, backups, and parallel clusters. We'll cover a fully worked example of DR and also discuss obvious and non-obvious trade-offs.
Every site is a little different--this webinar will provide you the tools to implement a DR strategy that works for you.
