The Couchbase Server 5.0 release now includes advanced profiling and monitoring capabilities, particularly for N1QL queries, which enable developers to better understand the performance of their applications. The Query Workbench provides a visually appealing interface for running N1QL queries, allowing users to quickly identify complex operations that consume significant resources. By analyzing the query plan, developers can gain insights into the efficiency of their queries and optimize them accordingly. This release also includes improved index management, which enables developers to create and manage indexes more efficiently. The new features are made available for download, and the author invites feedback from users who have tried out the developer preview versions earlier this year.
