Now the goal is to create a couchbase bucket name named Restful-sample for the application, which has an appropriate index for executing the N1QL query. In Couchbase's administrator interface, select Data Buckets, and then select Create New Data Bucket. Give the bucket a name and define the size of a storage space. Create a bucket in

. Without a single point of failure, no single point will cause data to be inaccessible. Read and write loads can be distributed evenly across different nodes of the system. Support for asynchronous persistence facilitates rapid recovery and can even be used directly as a key/value database. Often when communicating with friends in the industry, you will mention using the key segmentation method to do capacity expansion and load balancing. However, there are many problems with static key segment
