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!

Software Architecture Conference 2025 Talk: What Does “Cloud Native” Mean for Databases? Let’s Look at Code and Find Out!
Our CEO, Robert Hodges, is presenting the talk What Does "Cloud Native" Mean for Databases? Let's Look at Code and Find Out! at the Software Architecture Conference 2025, which will be live-streamed across platforms like Facebook, LinkedIn, Twitter, Twitch, and CSharp TV.
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 analytic 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.

FroSCon 2025 Talk – FinOps: Cloud Billing and Usage with ClickHouse
Our colleague, Denys Kondratenko, presented the talk FinOps: Cloud Billing and Usage with ClickHouse at the FroSCon 2025.
Managing costs and billing across numerous Cloud-managed Kubernetes clusters presents significant challenges. In this talk, we’ll explore these challenges and discuss solutions using ClickHouse, OpenCost, and how a unified FOCUS schema helps with it. Leveraging ClickHouse’s capabilities, we’ll demonstrate how it efficiently imports diverse Cloud billing data streams. Additionally, we’ll delve into how OpenCost addresses the complexities of real-time cost management within a multitenant architecture. Join us to uncover practical insights into optimizing cloud costs effectively
Five Things Every New ClickHouse® User Should Know (Part 2: Admin)
You just built the world's best ClickHouse app. Great. Now you have to run it!
This talk covers 5 important things you should know about ClickHouse admin to keep applications healthy and fast. We'll cover where to run production systems, how to manage replicated tables, modifying schema without sorrow, upgrading ClickHouse itself, and where to look when ClickHouse servers go bad.
Like our previous webinar on applications, there will be plenty of time for questions. We have helped thousands of engineers run ClickHouse at scale.
Join us and find out how it's done!
Open Source Summit Europe 2025 – Amsterdam Talk – Modern Application Debugging: An Introduction to OpenTelemetry
Joshua Lee - Open Source Developer Advocate at Altinity, will be speaking at Open Source Summit Europe 2025 in Amsterdam about Modern Application Debugging, and he will be offering an introduction to OpenTelemetry.
The talk offers insights into OpenTelemetry's tools and protocols, helping developers better utilize its capabilities for observability in cloud-native applications. The talk demonstrates how to instrument and observe microservice applications on Kubernetes, which is crucial for optimizing and debugging modern cloud-native systems. By highlighting the integration with tools like Jaeger and Prometheus, it shows how OpenTelemetry can be effectively used within the broader CNCF ecosystem to analyze telemetry signals.

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.
