19:45 〜 20:15 900K records per second with Ruby, Java, and JRuby Hiroshi Nakamura (@nahi)

Treasure Data is cloud analytics infrastructure. As of the beginning of July 2015, it stores 16 trillion records of customers data, and grows by 900,000 records per second. For handling this data, we are leveraging Ruby, Java, JRuby and many OSS components. In this presentation I'll introduce the system architecture and will discuss how we utilize these languages and OSS components to create a robust, performant, and flexible infrastructure.
