Redis TTL vs "allkeys-lru" eviction policy
<p>I have a question on Redis cache's behavior. Kindly clarify -</p>

<p>Say, for a key "xyz" if the TTL is set to 15 minutes.
And, if its eviction policy in server level is  set to "allkeys-lru". Does expired items(cause of TTL) EXPIRE or WAIT until the memory is full?</p>
