Backups can be run on a running node or on a clus

Couchbase is an open-source, distributed, document-oriented (document-oriented) NoSQL database with built-in Memcached services.

First, IntroductionThe Cache system most used by the C # industry today is mainly memcached and Redis.These two Cache systems can be said to be a more mature solution, but also a lot of system of course choice. Memcache is basically a standard for development, but for memcache clusters, many on-line deployments are still very thin. Several problems exist: not robust, data insecure, configuration changes can result in access anomalies, backing data consistency, Memcached does not support persiste

Similar to SQL (Structured Query Language), Cassandra will also provide Cassandra query statements (cql) in future releases ). For example, if the keyspace name is websiteks and cql is used: Use websiteks; Query the value of column family with standard1 and key as K: Select from standard1 where key = "K "; Update the value of column family to standard1, key to k, and column to

C # distributed Cache Couchbase use Introduction ofCouchbase At present, the most used Cache system in C # industry is mainly memcached and Redis.

. 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
