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.
