That's not correct 100%. ZF2 cache storage adapter doesn't change TTL behavior of the storage itself. So if the storage itself (like memcached, apc, xcache, ...) supports it the ZF2 cache storage adapter supports it, too. > I'm using per-item TTL all throughout a ZF1 app which I'm currently > migrating to ZF2 and desperately need to be able to do this.

The TTL is an option of a storage adapter as it's an option how the storage should handle items in it. If you have different TTL definitions normally you have different types of items which means you would need different configurations and storage instances. If you don't like that you need to write your own simple wrapper against a storage as @Ocramius prototyped here: https://github.com/zendframework/zf2/pull/5386#issuecomment-29381538 > At some point in the discussion, Matthew Weier O'Phinney suggests: > "Implement a plugin to add Item based TTL for storages not supporting it > natively" > > Unfortunately, as I mention on my > comment<https://github.com/zendframework/zf2/pull/5386#issuecomment-34491161>, > I don't know how to write this kind of plugin.

As @weierophinney pointed out "... for storages not supporting it natively" - it's a great way of implementing it to make that behavior available for storages like the filesystem or dba. It doesn't magically change the API and allows a TTL argument ... -> it needs to fetch the configured TTL option, calculate the expected expired time in base of current time + TTL and store it together with the item. On reading it needs to check the stored expire time and return a "Item not found" behavior in cases it's expired. An implementation would look similar to the current serializer plugin. Currently I don't have enough time to do some more work I'm interested in as we born our (first) adorable daughter :) But I could assist :) > Thanks!
