HSET

HSET

HSET key field value [field value ...]

Available since:

2.0.0

Time 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.

ACL categories:

@write, @hash, @fast,

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.

Examples

HSET myhash field1 "Hello"
HGET myhash field1
HSET myhash field2 "Hi" field3 "World"
