Hello,<br><br>I saw these proposed features for the Hackathon. Unfortunately I can't take in person, wrong continent for me.<br><br>I would like to suggest a feature which would probably address these issues well: tagging keys. Each key would have 0...n tags assigned to
<br>it. Flushing keys could be done by asking memcached to flush all keys with a certain tag.<br><br>The usage scenario: lets say we have a DVD. We have a number of keys related to this dvd, maybe recommendations, comments, categorization
<br>etc. I could tag each of these keys with the id of the DVD (dvd:1234). Then I would tell memcached to flush all keys with the tag dvd:1234,<br>causing the database to recalculate all data relating to dvd 1234 on the next access.
<br><br>Zend implemented similar functionality in their new framework:<br><a href="http://framework.zend.com/manual/en/zend.cache.theory.html#zend.cache.tags">http://framework.zend.com/manual/en/zend.cache.theory.html#zend.cache.tags
</a><br><br>The wildcard deletes could be done this way, more efficiently than looping through the whole cache to see if a regex matches. Multidimensional arrays could be partially simulated by using tags.<br><br>I hope someone is interested ;-)
