I just started using memcached with applications accessing it via the
Perl API. We really like it!
I was reading the archive and there is nothing in the docs that I have
found the explains expiry and item life times.
1) if I don't set and expiry for an item under what conditions, if any
will if get removed from the cache other than an explicit delete operation
2) we set an expiry of 7 days for all items, but are running out of
cache space, is there away to expire cached items early, like everything
that is greater than 5 days old
3) is there a way to configure the memcached to automatically expire the
oldest items or least used items to free space for newer items?
4) items sizes, the bulk of the items in out file cache that is getting
replaced are in the 500-1000 byte size (~90% count-wise) using about 75%
of the space and we have 5K-20K items (~9% count-wise) with say about
~1% in the 100-200K size. Are there any issues or concerns I need to be
aware of regarding these?
