Hi All, Thank you for the updates. I have been doing a lot of reading on memcached and I am trying to find a way I can find out what is the oldest key. Is there a way I can do this? Kind Regards Gurdipe Kind Regards Gurdipe Email: gurd...@veeqo.com Mobile: 07879682511 Home: 01656749236

As was answered, there's no built-in way to determine when a key was set. Furthermore, memcached itself doesn't track when the oldest key changes. The only way to approximate the behavior you want is to store the set times in each value, get all possible keys, and then do the comparison yourself.

I don’t think there’s a way to figure out when a given key was written. If you really needed that, you could write it as part of the data you stored, or use the ‘flags’ field to store a unixtime timestamp. You can get the age of the oldest key, on a per-slab basis, with ‘stats items’ and looking

The only data stored are when the item expires, and when the last time it was accessed. The age field (and evicted_time) is how long ago the oldest item in the LRU was accessed. You can roughly tell how wide your LRU is with that. On Mon, 12 Jan 2015, 'Jay Grizzard' via memcached wrote: I

Ack! You are, of course, right. I looked at the protocol documentation and completely failed to engage my brain enough to realize that the protocol documentation is… imprecise. Or at least unclear. Or at least lacks an appropriate definition of ‘age’. My bad! -j On Mon, Jan 12, 2015 at 12:14
