The Index Advisor service has released its February update, addressing several bugs to enhance its functionality. This service offers index recommendations to optimize query performance, making it useful for database administrators, developers, and architects. It is particularly beneficial for those who want to avoid manually understanding index creation rules, do not wish to upgrade to the latest Couchbase version, or are using older versions such as 5.5 or 6.0. Notable improvements include support for virtual keyspace operations, removal of identifiers in Meta() expressions, clearer error messages, and improved handling of queries with the USE index keyword. The update ensures that users receive monthly fixes and enhancements, aiming to improve query performance and productivity without requiring schema or data uploads. Feedback on the Index Advisor's recommended indexes can be provided through comments on the related blog.
