"Mapper API is built completely on top of public Google App Engine APIs, this API is only the first component of App Engine's MapReduce toolkit, but can be extremely useful on its own," stated Google…."Mapper API can be of use to many developers who would otherwise need to build their own tool for doing large scale data manipulation. In addition to taking care of distribution of these jobs over task queues, it provides ability to store state, batch datastore writes via mutation pools, and ships with an easy to use administrative interface for job management, all optimized for constraints of App Engine's dynamic serving environment."
