The HEXPIRE command allows manipulating the expiration time for existing hash fields.
When set, the expiration time of a hash field will determine when the field will be automatically deleted.
Note, that providing a millisecond time of '0' will cause immediate expiration and deletion of the field(s).
Options
The HEXPIRE command supports a set of options that modify its behavior:
- NX — For each specified field, set expiration only when the field has no expiration.
- XX — For each specified field, set expiration only when the field has an existing expiration.
- GT — For each specified field, set expiration only when the new expiration is greater than current one.
- LT — For each specified field, set expiration only when the new expiration is less than current one.
