XDCR can be configured for data locality to improve performance in which data is served from the Couchbase cluster, which is physically closer to the user's location to provide faster data retrieval. It will ensure 24x7x365 data availability even if an entire data center goes down due to some disaster. You can use it to verify code changes in a test environment with the actual production data before moving to the production environment, enabling the developers to test applications on the production data.

Starting with the architecture of Couchbase to get you up and running, this book quickly takes you through designing a NoSQL document and implementing highly scalable applications using Java API. You will then be introduced to document design and get to know the various ways to administer Couchbase. Followed by this, learn to store documents using bucket. Moving on, you will then learn to store, retrieve and delete documents using smart client base on Java API. You will then retrieve documents using SQL like syntax call N1QL.
