Well, this one took ages. And whenever something takes me ages, rather than write it down in my personal notes, I prefer to put it out online for everyone with the same problem to easily find and benefit from.

It enables applications to work with thousands of nodes and petabytes of data. Hadoop was inspired by Google's MapReduce and Google File System (GFS) (wikipedia). I wouldn’t call it an alternative to mysql – they’re in completely different weight categories. I like to think of Hadoop as a complement – I think it’s closer to memcached in its functions than to mysql. Perhaps a hybrid of both but a unique beast nonetheless. If you’re serious about scaling, you owe it to yourself to start exploring Hadoop yesterday.
