Scaling Datastores at Slack with Vitess
From the very beginning of Slack, MySQL was used as the storage engine for all our data. Slack operated MySQL servers in an active-active configuration. This is the story of how we changed our data storage architecture from the active-active clusters over to Vitess — a horizontal scaling system for MySQL. Vitess is the present and future of Datastores for Slack and continues to be a major success story for us. From the solid scalability fundamentals, developer ergonomics, and the thriving community, our bet on this technology has been instrumental for Slack’s continued growth.
