Redis Command: GETEX
Get the value of the key and additionally set the expiration time for the key. This command can work without the expiration time part, in that case, it will behave like the “GET” command.
Redis
Redis Command: MGET
Get the string values of multiple keys. As we can pass multiple keys and get the values, so it is a very handy command when we work with lots of keys. This operation always returns values without any fail, as for the non-existing keys it returns nil.
Redis Command: SET
Set the string value of a key. The key is created if it does not exist already. If the key already exists, then no matter what the type of the existing data is, it will be overwritten. When a value is set(without any expiration time) for an existing key, then the existing TTL will be removed(if any TTL is already set).
Redis Command: GET
Get/retrieve the string value that is set for the key. It only works if the saved value is of type string. This command returns nil if the does not exist.
Redis Tutorials
Redis is an in-memory data structure storage system. The term REDIS represents Remote Dictionary Server. Here is the list of Redis tutorials.
Redis: Key Management
Redis is a key-based data structure storage system. This a key-value storage system, where we don’t have any table or rows or columns like a relational database. The whole modeling/storing/retrieving of data depends on the key. So naming the key becomes very important. Here is how to effectively name keys in a Redis database.
Redis: Access Control List(ACL) – [Complex Permission for Users]
In this article, we are discussing all the aspects of Redis ACL(Access Control List). Redis ACL allows us to set permission for a user, in detail. Permission for all the parts(key, command, channel etc.) can be set separately.
Redis: Password Authentication(AUTH) [Default User]
After installing the Redis server, our next task is to set up the authentication. In this article we are discussing- how to set a password for the default user in Redis. The default user name for Redis is “default”. The basic steps of authentication will work for the “default” user.
Redis: Installation [Docker / Linux / MacOS / Windows]
In this article, we are discussing different installation methods/processes of Redis. First, we are discussing the installation of Redis using Docker. This will work on major operating systems, as docker is available in all common OS. Then we are discussing the installation process on specific operating systems – Linux (Ubuntu), MacOS, and Windows.
