Couchbase Mobile 3.1 has been released, offering significant enhancements in mobile and edge computing through the introduction of cloud-to-edge support for scopes and collections, initially launched in Couchbase Service 7.0. This update allows developers to better organize and manage data by logically isolating it within buckets, similar to tables in a relational database, which simplifies data organization and access control, especially for those transitioning from a relational database environment. The release highlights various use cases demonstrating the advantages of scopes and collections, such as streamlined data organization, scalable multi-tenant applications, and high application density at the edge. The use of scopes and collections also facilitates data isolation and management within a single Couchbase Lite instance and improves metadata isolation in Sync Gateway, thereby enhancing data lifecycle management and reducing complexity. This version maintains compatibility with previous bucket-based models, allowing for a gradual transition to the new system. Additional enhancements and API changes are detailed in the release notes, with resources available for further exploration.
