This new version of Index Advisor service provides several key improvements and fixes, including support for TTL (time-to-live) metadata, index recommendations on covering indexes, adjusting the order of index keys for functional and array predicates, and more. The service is now available to users every month, with fixes and recommendations made available before the next maintenance release. The Index Advisor service aims to help database administrators, developers, and architects optimize query performance and meet SLAs by providing index recommendations without requiring users to create a bucket or upload schema or data. Users can find this service useful if they want to avoid reading index creation rules, need help creating indexes for their queries, or want to generate advice on indexes without downloading the latest Couchbase server version.
