Hi Folks
My understanding is that items will expire in two fundamental ways; if
a TTL was specified on the set or if the cache needs room and deletes
old items.
My quesions are:
Is this understanding fully correct ?
Is there a way to tell the cache that an item should be fully
persistent - i.e. don't throw it away for any reason ?
The second question relates to us being able to use the cache as a
storage area that only disappears if the daemon stops etc. This would
be very useful in our environment where we can cache stuff at start
up, share it across multiple processes/networks, and have enormous
impact on efficiency. Obviously not specifying a TTL on the set method
means it wont expire, but what about the situation where the memcached
needs space and deletes the oldest items ?
thanks
Grant
