The recently released Couchbase Kotlin SDK version 1.0 is designed to integrate seamlessly with Kotlin’s features, focusing on asynchronous programming improvements and offering a concise, idiomatic approach compared to its Java counterpart. The SDK allows users to connect easily to Couchbase's Capella Database-as-a-Service and perform operations such as querying and document retrieval using Kotlin's native support for default parameters and coroutines. The SDK's API design emphasizes flexibility and binary compatibility by leveraging sealed classes for mutually exclusive parameters, utilizing Kotlin's DSL for configuration, and employing the CommonOptions class to manage optional parameters. These design choices aim to simplify usage while maintaining compatibility and efficiency, ultimately providing a robust and user-friendly library that aligns with Kotlin’s strengths.
