At least the 2nd one is important to me. I have been calling this
feature 'name spaces' in my mind for awhile.
The basic concept is that all keys have an optional prefix. So, your
keys would look like "<name space>:<key>". If the name space is omitted
it uses the name space of 'global'.
For me this is important because we store many different types of
objects in memcached, and there is no easy way to clear just those types
I don't really want 'wildcards', because doing any type of regular
expression inside memcached in the path to Hellish pain, but I think a
prefix/name space system could be very helpful.
PS: I work for Ask Jeeves on Bloglines.com. We are doing thousands of
requests per second to our memcached servers, and they have made a huge
difference in the performance of our site. Thanks to everyone who works
