Spring Boot 1.4.0 MILESTONE 2 has been released, offering a first-class integration of Couchbase into the Spring Boot ecosystem. The integration allows direct recognition of the Couchbase SDK in the classpath, instantiating a Cluster and Bucket bean with autoconfiguration properties such as spring.couchbase.bootstrap-hosts, spring.couchbase.bucket.name, and spring.couchbase.bucket.password. Environment tuning options like IO endpoints, SSL support, and default sync API timeouts are exposed through additional properties. The Spring Cache abstraction now supports Couchbase 2.x implementation, couchbase-spring-cache, which integrates nicely with the previous section's autoconfigured Bucket for caches. The implementation allows storing data from multiple caches into a single Couchbase bucket by prefixing keys with cache names. Additionally, Spring Data Couchbase 2.1.0 has been released, including modifications that make integration with Spring Boot easier, such as autoconfiguring Spring Data to use the default Bucket created by Spring Boot. The release includes new features like optional automatic touch on reads, improvements to sorting and pagination, added support for auditing, and more.
