hexpire

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.
