it's been a long time, but it seems to be coming back to me.
i'm taking an app that was storing values in IPC Shared Memory, and irefactoring it to use memcached
it's been used by other people at catalyst.net.nz, so it's been well tested.
it's also used in this well known site called livejournal.com.
so, what is it?
- a daemon, start from command line
# ./memcached -d -m 2048 -l 10.0.0.40 -p 11211
- you connect tcp
- ->put($key, $value) in, ->get($key) values out, like a one level hash
- it keeps a cache in memory, all is gone when it's restarted
- has apis in a bunch of languages, perl, php, python, ruby, java, c, c#, protocol
the nifty bit for me, was the expiry...
I can set a value, and an expiry for that value... It'll remove the value from memory when it expires.. so i can put session data in there and not manage the expiry. It means expired session don't fill memory.
i can also distribute it across several servers (i haven't yet, but i can see the app expanding that way)
it's less arcane than IPC::SharedCache, mostly because it takes care of itself.
oh, and it came recommended by Ned

PERL is good. Puts hairs on your chest.
Incidentally, your HTML editor thing still looks skewhiff...
