Authentication uses RBAC with local users or LDAP integration. Couchbase Capella (the managed cloud service) provides API key authentication for programmatic access. The RBAC model supports fine-grained access control at the scope and collection level — appropriate for multi-tenant applications where agents need isolated data access.
Couchbase is a distributed NoSQL database combining document storage with SQL-like querying (SQL++/N1QL), full-text search, analytics, eventing, and mobile sync — services that typically require multiple separate systems. For agents building applications that need document storage, search, and offline-first mobile sync, Couchbase provides these capabilities in a single platform with a familiar SQL-like query interface rather than requiring MongoDB plus Elasticsearch plus a sync service.
Reliability is production-grade for enterprise deployments. Couchbase's distributed architecture provides automatic sharding, replication, and failover. The Cross Data Center Replication (XDCR) feature enables multi-region deployments for disaster recovery. Couchbase Capella provides managed availability with automated operations.
The REST API covers buckets, scopes, collections, documents, and cluster management. The Query Service exposes SQL++ (N1QL) for querying JSON documents with standard SQL syntax extended for nested data. Agents can perform joins, aggregations, subqueries, and window functions on document data. The Full-Text Search API provides search indexes without a separate Elasticsearch deployment. The Eventing Service enables server-side functions triggered by document changes.
Documentation is comprehensive and covers the SDK, REST API, SQL++ query language, and each integrated service (Search, Analytics, Eventing, Mobile). The SQL++ documentation is the most important reference for teams transitioning from SQL databases to Couchbase. Teams evaluating Couchbase versus MongoDB for document database needs should compare the SQL++ query capabilities, built-in search, and mobile sync features.
