Check out Brad Fitzpatrick’s Linux Journal article on memcached to better understand what I mean.
I I am currently working on memcached as a method of coordinating a group of servers, but came across Apache’s ZooKeeper along the way. It looks interesting and Yahoo uses it, so it shouldn’t be broken, but I’ve never heard of it before, so I’m a little skeptical. Also Has anyone else tried it? Any comments or thoughts?
ZooKeeper and Memcached have different purposes. You can use memcached for server coordination, but you have to do most of the work yourself. Memcached only allows coordination because it caches multiple clients Common data lookups used on the end. From reading ZooKeeper’s documentation, its focus is much more than that. ZooKeeper seems to provide support for server clusters, which is different from the cache clusters provided by memcached.
