The Couchbase Analytics Service utilizes the SQL++ query language, which is designed to work with semi-structured data and the JSON data model, being backwards-compatible with SQL. The service is currently in developer preview, with occasional breaking changes between releases, so this post aims to document those changes. Key updates include automatic bucket association, removal of the SHADOW keyword for dataset definitions, and a revised syntax for connecting and disconnecting datasets, now using CONNECT/DISCONNECT LINK instead of CONNECT/DISCONNECT BUCKET. Additionally, Couchbase is open source and free to try out, with various resources available on its developer portal, including sample code, tutorials, and forums for support.
