20th ClickHouse Meetup took place in Amsterdam, which appeared to be a convenient location for people from all over Europe to join the event, including Austria, Czech Republic and Germany. We were also glad to see people from many local companies including Booking.com, Crobox, Marktplaats (eBay), MessageBird and others.
Interest in ClickHouse among Chinese experts is growing rapidly. It was second ClickHouse Meetup in Beijing this year and the venue was more than full, it could fit only about 170 people out of 500 who signed up and around 2000 more joined the live translation online. Many Chinese companies have already adopted ClickHouse in production and are willing to share their experience.

Last year there has been an OLAP algorithm contest in China organised by Analysys. The team who have shown the top results and won the competition has been using ClickHouse as core of their solution. Other teams were mostly using different technologies and didn't really know much about ClickHouse at a time. When the final results were published, many people in China who participated in or were aware of this competition became really eager to learn more about ClickHouse. This spike of interest about ClickHouse in China have eventually lead to first Chinese ClickHouse Community Meetup that have taken place in Beijing.
All presentations are available for download at the event page.
After Percona Live 2017, Yandex ClickHouse team stayed for one more week in San Francisco Bay Area to meet with local companies in person to talk about ClickHouse and how it can be applied to their tasks. On the last evening we even managed to organize our own meetup with active ClickHouse users in the area, not as large as we regularly host in Russia, but still had some very interesting discussions.
