Redis Development Environment Configuration _redis

The

Redis is a key-value storage system. Like memcached, it supports a relatively larger number of stored value types, including string (string), list (linked list), set (set), Zset (sorted set– ordered set), and hash (hash type). These data types support Push/pop, Add/remove and intersection-set and differential sets and richer operations, and these operations are atomic. On this basis, Redis supports a variety of different ways of ordering. As with memcached, data is cached in memory to ensure efficiency. The difference is that Redis periodically writes the updated data to the disk or writes the modification operation to the appended record file, and on this basis, it realizes the Master-slave (master-slave) synchronization. The
Redis is a high-performance key-value database. The emergence of Redis, to a large extent, compensates for the shortage of such key/value storage in memcached, and in some cases can complement the relational database well. It provides Java,c/c++,c#,php,javascript,perl,object-c,python,ruby,erlang and other clients, easy to use. [1]
Redis supports master-slave synchronization. Data can be synchronized from the primary server to any number of servers, from which the server can be associated with other primary servers from the server. This enables Redis to perform a single layer tree replication. Saving can be intentionally or unintentionally to the data to write operations. With the full implementation of the publish/subscribe mechanism, you can subscribe to a channel and receive a full message publishing record from the primary server when you synchronize the tree anywhere from the database. Synchronization is useful for the scalability of read operations and for data redundancy.
Redis's official website address, very good to remember, is Redis.io. (specially checked, the domain name suffix io belongs to the national domain name, is British Indian Ocean territory, namely the British Indian Ocean Territory)
Currently, VMware is financing the development and maintenance of REDIS projects.

If all is commented out, the memory data is not persisted.
