comment In MVC design, do I use a base class over an interface?
I'm unsure about PHP, so I can't answer that. I was answering it from the context of MVC design.

comment How do I go about data deduplication at scale?
@arnaud: The Mapping function would map the item to itself (e.g. return a pair <item1,item1>). The Reduce function would, for a pair of duplicate items, delete one of the items.

comment How do I go about data deduplication at scale?
@arnaud: The OP asked "What do you think can a viable approach be? Hashing? using divide and conquer type algorithms to exploit parallelism? I have these in my head, but it really gets giddy at such scale." It seemed to me that the OP was asking for other algorithms, which MapReduce is. The goal of my answer was to point the OP toward an algorithm which helps with deduplication. How the OP implements that is entirely up to them.
