Redis data persistence, redis dataIn general, there are two persistence solutions: RDB and AOF.The RDB method creates a time point-based snapshot for the dataset at a certain interval.The AOF method records the write operations received by the Server to log files. When the Server restarts, It replays these write operations to recreate the dataset. This method is similar to the statement-based binlog in MySQ

Redis Cache Set usesIn Redis, we can look at a set type as an unordered character set, and like the list type, we can also perform actions such as adding, deleting, or determining whether an element exists on that type of data value. It should be explained that the time complexity of these operations is O (1), that is, the constant time to complete the operation. The maximum number of elements a set can con

On implementation, only one thread is used to handle the specific memory data structure, to guarantee the atomic characteristics of its data manipulation commands, it also supports LUA based scripts, each Redis instance uses the same LUA interpreter to interpret the running Lua script, and thus the Lua script has atomic characteristics, This c
