I thought I’d compile a list of Redis commands that can be used to set strings. Each command has its own specific use, and so the command used will depend on the situation.
In any case, here are 14 commands that set strings in Redis.
Continue readingI decided to compile a list of commands that can be used to get the string value from a key in Redis. These are all string commands – commands that can be used when working with strings. In other words, the assumption is that the key holds a string value.
Continue readingIn Redis, the SUNIONSTORE command does the same thing that SUNION does, except that it stores the result in a key. More specifically, it takes the members of the set resulting from the union of all of the given sets, and stores them in the specified key.
In Redis, the SUNION command returns the members of the set resulting from the union of all of the given sets.
In Redis, the SREM command allows us to remove one or more members from a set.
In Redis, the SRANDMEMBER command returns one or more random members from the set value store at the specified key.
If you want to remove the random member/s from the set, use the SPOP command.
In Redis, the SPOP command removes and returns one or more random members from the set value store at the specified key.
This command is similar to the SRANDMEMBER command in that it returns one or more random members from a set, but SPOP removes it, whereas SRANDMEMBER doesn’t.
In Redis, the SMOVE command moves a member of a set from one key to another. In other words, the member is removed from the source set and added to the destination set.
In Redis, the SMEMBERS command returns all members of a given set. We specify the key name of the set when we call the command.
In Redis, we can use the SMISMEMBER command to find out whether one or more members are in a given set. It’s similar to the SISMEMBER command, except that it allows us to check more than one member at a time.
The SMISMEMBER command was introduced in Redis 6.2.0.
