Redis is an open source, C-based, memory-based, and persistent, high-performance NoSQL database, and it also provides APIs in multiple languages. Recently, Redis 3.0 after 6 RC version, its official version finally released. The most important feature of Redis 3.0 is the support for Redis clusters, which has been signi

Try Redis: getting started with RedisOpening Redis is a NoSQL database that stores data using key-value pairs. Key-value pairs store data based on a key. Then you can use this key to retrieve the stored value. AvailableSETThe command uses the key 'servername' to store the value 'fid ': SET servername 'fido' In this way, the data is stored and can be used later.GETRetrieve the stored data: GET serverna

Redis Research (17)-SORT sorting, redis research sort sorting 1. Set Operations of Ordered Sets The set type provides powerful set operation commands, but the ordered set type is required if sorting is required. When designing Redis commands, the author of Redis considers the use cases of different data types. For feat

The previous article explains the process of building the Redis cluster based on Redis cluster, and continues to explain the increase and decrease of node in the Redis cluster below. adding nodes in a cluster Let's test again, add a new node, in 2 cases, 1 as the primary node, 2 as a node from the node. Let's try this separately: Create a new 7006 node to join as

Label:Overall overview Redis is a database, like a structured data server . As compared to the rows in the MySQL action table, the MongoDB operations document in the collection is accessed in such a way that Redis accesses the data by key . It is a key-value type of NoSQL database. Because the data is stored in memory, access is fast. (Of course, for the sake of some data security, you can also bac

Redis cluster, redis ClusterCluster understanding In fact, many places may be exposed to the concept of clusters. Why is there a cluster? Simply put, it is just how good people do things. It was originally a task that a person had to work hard to complete. Now it is done by ten people, and ten people can do it easily. In the case of massive data, today, if you want to process and store more data, but do

Redis, like MySQL, has a very powerful master-slave replication feature, and it also supports a master that can have multiple slave, while a slave can have multiple slave to form a powerful multi-level server cluster architecture.　　　　　　　　　Redis's master-slave replication is asynchronous and does not affect master's operation, so it does not degrade the processing performance of Redis. In the master-slave ar
