Concept: "Cloud" MergeTree Tables
23 November 2018, 15:06

The main property of the MergeTree cloud tables is the absence of manual control over the sharding scheme of data on a cluster. The data in the cloud tables is distributed around the cluster on its own, while at the same time providing the locality property for a certain key.

ClickHouse Community Meetup in Beijing on January 27, 2018
8 February 2018, 20:24

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.
