Altinity Event: Real-Time Data Lakes

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 from a range of experts as they share current problems and solutions while navigating the transition from closed storage models to open table formats like Apache Iceberg.
​​Join us in London for an evening with experts from ClickHouse®, AWS, and Snowflake. Learn how to build high-performance real-time data lake systems. Networking to follow presentations. Food and drink provided!

Open Source Analytics Conference 2025: AI-Powered Alert Analysis with ClickHouse Cloud

The Open Source Analytics Conference (OSA CON) is the go-to conference for all things open-source analytics. Learn, share, connect, and explore the latest in data ingestion, orchestration, databases, infrastructure, governance, visualization, and AI. Join the doers of the modern data stack.

SeaGL 2025 Talk: What’s a Data Lake and What Does It Mean For My Open Source Analytics 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 SeaGL 2025 Conference. The 2025 conference will be held November 7-8.
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.

Data Science Summit 2025: Super-fast Access to Unstructured JSON: the ClickHouse® Way

Maciej Bak - Support Engineer at Altinity - speaks at Data Science Summit 2025. The origins of the Data Science Summit date back to 2014, when the first Data Science Warsaw community meeting was held. It was the popularity of these periodic meetups that contributed to the decision to organize the first edition of the conference, and its success led to subsequent editions. Currently, DSS is the largest Polish community focused around *data* field.
Maciej's talk - Super-fast Access to Unstructured JSON: the ClickHouse Way is about indexing JSON, which has always been a challenge. Even databases built around documents, like MongoDB, struggle to make unstructured data both flexible and fast. Until now, ClickHouse users had to lean on pipelines, materialized views, or Map hacks to query JSON at scale.

Open Source Experience 2025: Scaling Analytics with ClickHouse® in Cloud-Native Environments

Alkin Tezuysal speaks at Open Source Experience. The conference is the Tech – Usage – Business event dedicated to Open Source IT solutions, bringing together over 4,000 professionals and players in the digital sector over 2 days!
Open Source Experience focuses on open source technologies, solutions and challenges in France and Europe, and highlights the driving role of open source innovations in the digital transformation of organisations in technologies such as AI, Data Management, Cloud, and Cybersecurity.
ClickHouse is a high-performance columnar database designed for analytical workloads, but running it efficiently in cloud-native environments presents unique challenges. Alkin's talk explores the architecture of ClickHouse and provides strategies for scaling it to handle massive data streams in containerized and distributed systems.
