redis commands

The following are some of the most commonly used basic commands under the Redis command line, which you can refer to for your study: 1. "Set key value" is stored in a key and value. such as: Set MyName reson2. "Get Key" reads the value of a key.3. "Del key" deletes a key.4. "Del key1 key2 ... keyn" deletes more than one key. such as: Del myname1 myname25. "Exists key" to determine whether a key exists.6. "

---llen command: Return the length of the list, here MyList only 4 data left, so the output is 4127.0.0.1:6379>lindex mylist 3---lindex command: Gets the data for the given position, where the data at coordinates 3 is "2", so the result is 2.4. The list data modification command in Redis: LSet127.0.0.1:6379>lset mylist 2 zlh---lset command: Set the value of subscript 2 to ZLH and return an error if the subscript value goes out of range or an empty lis

Redis- Remote Dictionary Server, which is an open source, written in ANSI C language, supports the network , can be based on memory and persistent log type, Key-value Database and provides multiple language APIs that we can use to build high-performance, extensible Web applications.Has the following characteristics: exceptionally fast: the Redis database is completely in memory , so processing is

commands in one client-initiated transaction can be executed consecutively, without inserting other client commands in the middle. When a client issues a multi command in a connection, the connection goes into the context of a transaction, and the subsequent command is not executed immediately, but is placed first in a queue, and Redis executes all the

The Flushall flushdb command clears the data and never fails, which is dangerous for online clusters. The KEYS * command, when used when the data scale is large, can seriously affect redis performance and is very dangerous. What if these risks are fundamentally circumvented? Redis provides a very simple and efficient way to set the disable commands directly in

The Flushall flushdb command empties data and never fails, and is very dangerous for online clusters. The KEYS * command, when used with large data sizes, can severely affect Redis performance and are also very dangerous. What if these risks are fundamentally circumvented. Redis provides a very simple and efficient way to set up disabling these commands direct

Redis provides a variety of commands to operate databases and various data types. (1) keys returns all key values that meet the given pattern. For example, to return all keys, use keys.
