HSETEX
Syntax
HSETEX key seconds field value [field value ...]
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: @read, @hash, @fast
Warning: Experimental! Dragonfly-specific.
Similar to HSET
but adds one or more hash fields that expire after specified number of seconds.
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.
In any case, the expiration of the field is updated according to the latest value and the current clock.
Return
Integer reply: The number of fields that were added.
Examples
dragonfly> HSETEX myhash 5 field1 "Hello"
(integer) 1
# wait for 4 seconds
dragonfly> HGETALL myhash
1) "field1"
2) "Hello"
# wait for 1 seconds
dragonfly> HGETALL myhash
(empty array)
