Big Data Conference Europe is a four-day event that focuses on technical discussions in the areas of Big Data, High Load, Data Science, Machine Learning, and AI. The conference comprises a series of workshops and sessions, aimed at bringing together developers, IT professionals, and users, to share their experience, discuss best practices, describe use cases and business applications related to their successes. The event is designed to educate, inform, and inspire – organized by people who are passionate about Big Data and Data Exploration.
Our colleague, Alkin, will present the talk: Running Non-Cloud-Native Databases in Cloud-Native Environments: Challenges and Solutions.

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.

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.
