Couchbase's data platform is used in various ways by its customers, including empowering workers with always-on and reliable data on the go, building modern web applications, and delivering high-performance responses even at extremely high volumes. The company recently announced the expansion of its Database-as-a-Service (DBaaS) Capella to support memory-only buckets, allowing customers to store data only as a cache and not write it to disk. This feature is useful for transient or ephemeral data that may not need permanent storage, reducing performance issues and costs. Memory-only buckets can be used in various use cases such as session management, caching mechanisms, anonymous information management, and enhancing security and privacy. Customers can set up memory-only buckets by defining them during bucket creation and controlling the Ejection Policy and durability level. With this feature, Capella makes it easier for customers to get started with Couchbase and take advantage of its valuable tools for improving performance, cost, flexibility, and scalability.
