Redis HRANDFIELD Command
The Redis HRANDFIELD command allows us to get a random field from a given key.
The command accepts several arguments that allows us to specify the number of random fields returned, whether to include the same field multiple times, and whether or not to include the values with each field returned.
The HRANDFIELD command was introduced in Redis 6.2.0.
Redis HEXISTS Command
In Redis, the HEXISTS command allows us to check whether a field exists in a given hash. We pass the name of the key and the field to the command, and it returns 1 if the field exists, and 0 if it doesn’t.
Redis HKEYS Command
The Redis HKEYS command returns all fields in the hash stored at the specified key.
Redis HDEL Command
In Redis, the HDEL command enables us to delete one or more fields in a hash. It deletes the specified field/s at the specified key.
If the field doesn’t exist, it’s ignored. If the key doesn’t exist, it’s treated as an empty hash and 0 is returned.
