In Redis, the OBJECT ENCODING command returns the internal encoding for the Redis object stored at the specified key.
How to Increment a Floating Point Number in Redis
The INCR command is commonly used in Redis to increment a value by one. And the INCRBY command can be used to increment a valued by a specified integer. But neither of those commands let us work with floating point numbers.
If we want to use floating point numbers, we can use the INCRBYFLOAT command.
Redis RANDOMKEY Command Explained

Redis KEYS Command Explained
In Redis, the KEYS command returns all keys in the database matching a given pattern.
Redis DUMP Command Explained
The Redis DUMP command serialises the value stored at a specified key in a Redis-specific format and returns it to the user.
The serialisation format contains a 64-bit checksum that is used to make sure errors will be detected. The values are in the same format used by the RDB. Also, an RDB version is encoded inside the serialised value, so that different Redis versions with incompatible RDB formats will refuse to process the serialised value.
Redis TOUCH Command Explained
The Redis TOUCH command alters the last access time of a key or keys. It allows us to alter the access time of a key without accessing it directly.
Subtract Hours from a Time Value in SQLite
In SQLite, we can use the TIME() function to subtract one or more hours from a time value.
For datetime values, we can use the DATETIME() function.
Redis EXISTS Command Explained
In Redis, the EXISTS command checks whether the specified keys exist. It returns an integer reply with the number of keys that exist.
We can use the command to check for the existence of one key or multiple keys.
