Couchbase is a NoSQL database that offers various features for administrative tasks, deployment, and data management. It has a Restful API for automation of operations, can be quickly deployed on AWS, and supports deployment on Kubernetes or OpenShift with an Operator for infrastructure management. Couchbase can scale massively by combining high performance with linear scalability through architectural features such as Transparent shards, multidimensional scaling, master-less architecture, Database Change Protocol, No single point of failure, etc. It also provides full-text search indexes, supports end-to-end data compression, and allows auditing of queries. Additionally, it has a feature called Response Time Observability which logs slow requests with details for identifying poor performance.
