This year's FOSDEM conference saw ClickHouse make a strong showing in Brussels, with several team members attending and multiple talks covering topics from powerful new JSON data types to the challenges of fuzzing databases. The conference, one of the biggest open-source events in the world, brought together thousands of developers, engineers, and open-source enthusiasts for knowledge-sharing, project showcases, and deep technical discussions. ClickHouse was well-represented at FOSDEM, with talks covering the new powerful JSON data type, database fuzzing challenges, and the creation of an rDNS map to understand internet structure. The event also included a community dinner where users could meet, discuss database internals, and share ideas over great food and drinks.
