Couchbase 7.0 introduces Scopes and Collections, enhancing microservices and multi-tenant application deployment by offering a more flexible data organization system. Scopes and Collections function as logical containers within a Couchbase Bucket, akin to tables and schemas in relational databases but with the added flexibility of JSON documents. This release allows for independent lifecycle management, improved security controls, and simplified N1QL queries. The new system supports up to 1,000 Collections and Scopes per cluster, facilitating the consolidation of microservices and tenants while maintaining logical and security isolation. The deployment architecture needs to consider these limits, as the number of Scopes and Collections is restricted at the cluster level. Additionally, Couchbase 7.0 enhances multi-tenancy by allowing different levels of isolation, resource sharing, and backup/restore options, aligning with modern SaaS application requirements.
