Discover the open-source tools necessary to deploy, monitor, manage, and utilize your analytical ClickHouse database on Kubernetes. Whether you're using a cloud-managed Kubernetes solution or have your deployment, this talk will provide invaluable insights into navigating the open-source ecosystem for ClickHouse. We will explore the key components needed to seamlessly integrate ClickHouse into your Kubernetes environment and maximize its analytics and data processing potential.
The benefit of the ecosystem: Attendees will gain essential insights into deploying ClickHouse databases on Kubernetes using open-source tools. Whether using cloud-managed Kubernetes or self-deployed environments, join us to streamline your ClickHouse deployment and contribute to enhanced efficiency and innovation in data management within the ecosystem.
Kubernetes Cluster Logging with the OpenTelemetry Collector and ClickHouse®
Logs may be looked down upon by today’s observability thought leaders, but there is a reason they are the first pillar of observability: there’s a relevant log message at the end of almost every debugging journey! Collecting those logs from applications and infrastructure in a standard format is now trivial thanks to the OpenTelemetry Collector, and we get to keep it in the same format — and potentially the same database — as our other telemetry signals like traces, metrics, and profiles.
In this webinar, we’ll show how to use the OpenTelemetry Collector to gather all application and cluster logs from a Kubernetes cluster. We’ll use ClickHouse to store and query our logs and Grafana to visualize trends. By the end of the session, you’ll have everything you need to standardize your cluster logs on the most forward-looking format available today: OpenTelemetry.
The Doctor Is In–Quick First Aid for Broken ClickHouse® Clusters
Properly managed ClickHouse servers are well-behaved, but every cluster runs into problems at some point.
In this webinar, we'll introduce common issues that require admin intervention or even application changes. Topics include too many connections, too many parts, lost replicas, stuck mutations, and too many detached parts on startup. In each case, we'll explain the problem, show you the symptoms, and give you the standard cures.
There will be extra time for questions, so bring your favorites. We'll be happy to offer opinions.

State of Open Con® 25 London: What’s a Data Lake and What Does It Mean For My Open Source Stack?
The UK's Open Technology Conference, Open Source Software, Open Hardware, Open Data, Open Standards, & AI Openness is happening on the 4th and the 5th of February 2025, in Sancroft, Rose St, Paternoster Sq., St Paul's London EC4M 7DQ.
Our CEO, Robert Hodges, will be presenting the talk:
What’s a Data Lake and What Does It Mean For My Open Source Stack?
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.
TiDB – Real-Time Analytics and AI at Scale Meetup
Join us in New York City for an evening of forward-thinking engineering and applied infrastructure innovation. At this meetup, you’ll hear from leading voices in the analytics and distributed database space on such topics as: How ClickHouse® and Apache Iceberg are enabling sub-second analytics over 100+ petabytes of data through stateless swarm clusters. How scalable, persistent memory architectures—powered by TiDB—are reshaping what’s possible in AI systems that think beyond the prompt. From streaming analytics to memory-enabled agents, this meetup is ideal for engineers, architects, and builders pushing the boundaries of data performance, intelligence, and design.
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.
Open Source Analytics Festival
OSA Con is proud to announce an evening devoted to four of the most popular analytic open source technologies on the planet: ClickHouse®, Presto, Gluten, and StarRocks. We'll have presentations from community experts followed by a panel featuring audience questions to the presenters. There will be refreshments, drinks, and lots of time for networking with other database developers. Join us!
* OSA Con = Open Source Analytics Conference. The CfP for our main Conference in November is open now!
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.
