What’s Hot?

The Couchbase Java SDK 3.0 is a complete rewrite of the 2.x API, providing a simpler surface area and adding support for future Couchbase Server features like Collections and Scopes (available in Couchbase Server 6.5 and 6.6 as a developer preview). The (reactive) API also migrated from RxJava to Reactor, along with other improvements to performance, logging, debugging and timeout troubleshooting.
