ClickHouse is a popular open-source database management system that has gained significant attention in recent years due to its ability to provide subsecond latencies for analytics. The Percona Live conference featured three talks on ClickHouse, with only one coming from Yandex, and offered a chance for attendees to engage with the community at the Altinity-sponsored booth. Alexander Zaitsev, CTO of Altinity, provided an overview of ClickHouse along with case studies and best practices, while Aleksey Milovidov, lead developer from Yandex, discussed unique features of ClickHouse in his presentation. Additionally, data engineers from MessageBird showcased their use of ClickHouse for analyzing message delivery processes, highlighting the system's flexibility and capabilities.
