What is the main difference between a MapReduce Job and Batch Job when there is no Reduce Step? From the snippet below I don’t get what you mean with “Data Backed by an entity type”.
In my case I want to apply a function F to all the instances of a Type A. Type A has a reference field that points to data of another Type B and F uses fields of A and B to do some processing and ouptut some function. Basically I need distribute the application of F, what should I use? A Batch Job or a Map Reduce (without Reduce)?
I would say a MapReduce Job, but I am not sure…
Thanks a lot!
