Today, I saw that Hackszine’s Jason Striegel has postsed a blog post about Memcached and MySQL.
Well, basically Memcached is an open-source software for your web server that allows you to cache almost any MySQL query.
In other words, it caches your MySQL queries. But to do this, you do need to check the Memcached cache before doing the actual MySQL query.
So what’s the point?
Memcached is also designed for server-farming, meaning you are only limited by number of servers and gigs of ram.
Unlike PHP accelerators, Memcache is really a database cache, thus can give you some extra performance if you implement it right.
Now if the developers at WordPress started implementing Memcache, that’d do a lot of good for bloggers.
That said, if you want to explore Memcached, you can check out Jason post over at Hackszine.
