SREcon21 - Cache for Cash—Speeding Up Production with Kafka and MySQL binlog

Cache for Cash—Speeding Up Production with Kafka and MySQL binlog Barak Luzon, Taboola How can you serve up-to-date information on a high scale production system? Our company provides content recommendations to billions of people. We have hundreds of frontend servers across 7 regions. They need to withstand a massive load of 500K HTTP requests per second while maintaining a fast response time. In order to do so, we rely heavily on in-memory caching. By design, caching has a tradeoff between data freshness and load. What if I tell you that you can have fresh data without creating the extra load of fetching it? Our journey started with a "fast track" we created using Kafka and Mysql binlog, and ended up with a huge performance and yield improvement across thousands of services with blazing fast information updates.
