What is Google App Engine
Google App Engine is a platform for building scalable web applications and mobile backends. It has a efficient Map Reduce Library that processes large set of data in map and reduce pattern in parallelism. This project will use this library to process a serious of searching history and produce a recommendation list for user.
Map and Reduce Library on GAE
In Map and Reduce Library, user code is only required for mapping and reduce function. The platform will shuffle and rearrange data order to make the upcoming reduce process extremely fast. This also reduces a lot of development work. For further boosting, the shuffle part can be rewritten to boost up the speed.
The original source code is here.
