Delivery Hero has provided the venue for a meetup of the ClickHouse community at their HQ, which is one of the main limiting factors on how often such meetups can happen worldwide. The event had around 50 attendees from 75 sign-ups, exceeding typical rates. Alexander Zaitsev gave an overview of ClickHouse, while Gleb Kanterov discussed its usage for experimentation metrics at Spotify. The company's approach to conducting experiments and measuring their worth in production led to a framework scalable to thousands of metrics. Alexey Milovidov provided a technical talk on the inner workings of ClickHouse. The event was well-received by attendees who were eager to discuss topics beyond the talks. If your company is interested in hosting a similar meetup, you can reach out to the ClickHouse team for cooperation.
