- Usage:
-
HSET key field value [ field value ... ]
- Complexity:
- O(1) for each field/value pair added, so O(N) to add N field/value pairs when the command is called with multiple field/value pairs.
- Since:
- 2.0.0
Sets the specified fields to their respective values in the hash stored at key.
This command overwrites the values of specified fields that exist in the hash.
If key doesn't exist, a new key holding a hash is created.

"Hello"
127.0.0.1:6379> HSET myhash field2 "Hi" field3 "World"
(integer) 2
127.0.0.1:6379> HGET myhash field2
"Hi"
127.0.0.1:6379> HGET myhash field3
"World"
