Memcache maximum key expiration time

Question

What\'s memcached\'s maximum key expiration time?

If I don\'t provide an expiration time and the cache gets full, what happens?

Answer 1

On laravel config.session.lifetime setting that if set to be an equivalent of 30days above, will be considered as a timestamp (this will give an error of token mismatch everytime assuming that memcached is used).

To answer, memcached expiration could be set anytime. (Laravel's default setting (on v5.0) will set you to an already expire timestamp). If you did not set it, the defualt will be used.
