First, Redis introduction Redis is one of the most popular NoSQL systems, and it is a key-value storage system. Similar to memcache, but largely compensates for the lack of memcache, which supports a relatively large number of stored value types,

When the client connects to the server, the client can send a command request to the server. To send a command request from the client to the command to be processed by the server and return the result to the client, the process has the following

5 usage Scenarios for Redis Redis is a powerful storage of memory data structures, including databases, caches, and message brokers for a variety of purposes. Most people often think of it as just a simple key-value store, but in fact it has more

In addition to being used as cache data, Redis can also do these Redis should be one of the most popular NoSQL databases at the moment. Redis is typically used as a cache component for caching data. However, in addition to caching data, there are

Redis uses its own implementation of the event separator, high efficiency, the internal use of non-blocking execution mode, throughput capacity is relatively large. However, because the general memory operation is simple access operation, the

Java Web projects, which do not rely on web containers for load balancing, must address session sharing issues. There are many online solutions, but I think the use of Spring-session +redis is the most efficient, do not have to reinvent the wheel,

The key in the Redis key-value pair is of type string. What does the Redis internal implementation do with string? The Redis bottom is written in C, for STIRNG does not directly use the C character array, but instead encapsulates a type of SDS. The

Redis's set is an unordered collection of type string. A collection member is unique, which means that the collection cannot have duplicate data. The collection in Redis is represented by a hash table, so the complexity of adding, deleting, and
