What is the difference between HSET and HMSET method in redis database

Question

In my application im using redis database.I have gone through their documentation but i couldn\'t find the difference between HSET and HMSET.

Answer 1

HSET key field value:

Sets field in the hash stored at key to value. If key does not exist, a new key holding a hash is created. If field already exists in the hash, it is overwritten.

HMSET key field value [field value ...]

Sets the specified fields to their respective values in the hash stored at key. This command overwrites any existing fields in the hash. If key does not exist, a new key holding a hash is created.
