DigitalOcean has announced two new features for its Managed Database for Redis offering: the ability to add up to two additional nodes to existing clusters, and support for using standby nodes to serve read requests. These enhancements aim to increase scalability, performance, and availability of Redis clusters and applications, empowering developers to build more performant and scalable applications. Adding a standby node is simple and can be done through a guided process, while using standby nodes for reads can improve overall performance and responsiveness by offloading read traffic from the primary node.
