membase and TTL
I'm currently evaluating membase as a storage solution for content that has a defined TTL.
I'm currently testing with a TTL of 3600s the problem I see is that after 3600s the values are correctly expired and get request return no result but still membase seems to not release any RAM/disk resource, on top of that when I fill my available RAM quota for a bucket which is mostly full of expired values I get many NOT_STORED errors.
Also I noticed that shutting down and restarting the server all the expired entries "reappear".
I would like to understand if membase is supposed to work with entries having a TTL or not.
