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.

Aleksandar Aleksandrov and Felix Mattrat, data engineers from MessageBird, show how they use ClickHouse to analyze process of delivery of SMS and other kinds of messages:
