Couchbase Developer study guide
Couchbase Developer · Work through your exam, one topic at a time.
The Couchbase Developer credential is presented as a certification for software engineers, application architects, and backend developers who design, build, and operate applications on Couchbase's data platform. The vendor's public site frames Couchbase as "The Operational Data Platform for AI," spanning Capella, Couchbase Server, the Kubernetes Operator, an AI Data Plane, and Edge & Mobile products, with SDKs, tutorials, documentation, and a developer hub offered as learning resources. Because the vendor's certification page returned a 404 error at the time of retrieval, this page does not state a verified exam format, question count, duration, passing score, fee, retake policy, or validity period; those fields are marked for review rather than estimated. The four published study domains, each weighted 25 percent, are data modeling and querying; SDK and application development; cluster operations and administration; and mobile and edge development. The Couchbase Developer study guide has 4 sections and about 1,844 words.
01Couchbase Data Modeling and Querying
The Data Modeling and Querying domain tests whether you can design JSON documents for Couchbase and write SQL++ queries that use indexes efficiently. Expect questions on key design, embedding versus referencing, collection layout, index selection, and query consistency.
454 words, about 2 min02Couchbase SDK and Application Development
The SDK and Application Development domain tests your ability to connect an application to Couchbase, perform CRUD safely, handle concurrency and failures, and use transactions and durability correctly. Questions often present a code scenario or ask which SDK call or error-handling pattern fits.
475 words, about 2 min03Couchbase Cluster Operations and Administration
The Cluster Operations and Administration domain tests how Couchbase Server is structured and operated: services, vBuckets, replication, rebalance, failover, backup, security, and monitoring. Questions often ask what happens during a topology change or which administrative control prevents a specific failure mode.
449 words, about 2 min04Couchbase Mobile and Edge Development
The Couchbase Mobile and Edge Development domain tests offline-first application design with Couchbase Lite on the device and Sync Gateway as the synchronization and access-control tier. Expect questions on replication modes, channels, conflict handling, authentication, and on-device querying.
