The Couchbase Ruby SDK has been reintroduced due to popular demand, offering a simplified and high-performance API for connecting to Couchbase clusters from Ruby. This SDK supports features like Scopes and Collections, and is compatible with any MRI Ruby version from 2.5.0 and Couchbase server versions from 6.0.0. Installation is straightforward, with the beta version of the SDK available through a simple gem command, and it supports precompiled extensions for environments lacking a C/C++ compiler. The SDK enables easy connection to a Couchbase Server cluster and provides access to Buckets, Scopes, and Collections. It includes enhanced features for key-value operations, sub-document operations, and querying with the N1QL query language, as well as analytics capabilities for running complex ad-hoc queries. The SDK aims to facilitate the development of applications with improved efficiency and ease, inviting users to explore its capabilities and engage with the developer community for support and feedback.
