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.

Come learn about ClickHouse, our open source high-performance column-oriented database management system at a meetup on October 5, 2017 at the Park Inn at Alexanderplatz 7 in Berlin.
ClickHouse can generate custom data reports in real time and process billions of rows and dozens of gigabytes of data per single server per second. It works up to a thousand times faster than traditional approaches. ClickHouse is linearly scalable, hardware-efficient, fault-tolerant, and can be deployed across multiple data centers. Among other features, ClickHouse offers a user-friendly SQL query dialect with a number of built-in analytics capabilities.
Join us at the meetup to learn why hundreds of companies across Europe, US, and China are adopting ClickHouse. Through interactive talks, attendees will learn about product features, how ClickHouse can benefit them, and how to use this system in practice.
Attending the ClickHouse meetup is free. Please register to join us.

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.

For those who haven't heard, Percona Live is probably one of the largest international conferences about opensource database management systems, having 12 talk tracks in parallel. It's been around for many years and initially it was focused mainly on MySQL (and had that in it's name), but nowadays it is more generic and other products of this category get lots of attention too. Needless to say that for a relatively new player on the market like ClickHouse, it's been a great opportunity to spread the word about the technology and how exactly it allows to perform analytics on petabytes of data in real time.

Yandex.Metrica takes in a stream of data representing events that took place on sites or on apps. Our task is to keep this data and present it in an analyzable form. The real challenge lies in trying to determine what form the processed results should be saved in so that they are easy to work with. During the development process, we had to completely change our approach to data storage organization several times. We started with MyISAM tables, then used LSM-trees and eventually came up with column-oriented database, ClickHouse.
