persist

PERSIST

PERSIST key

Available since 2.2.0.

Time complexity: O(1)

Remove the existing timeout on key, turning the key from volatile (a key with an expire set) to persistent (a key that will never expire as no timeout is associated).

Return value

Integer reply, specifically:

1 if the timeout was removed.
0 if key does not exist or does not have an associated timeout.
