Even if they wanted to enforce it they'd have to prove it.
Otherwise patenting map reduce - which is practically one of the foundations of functional data processing - is down right silly
- bitdiddle 17y agoI agree completely. I would think there is enormous prior art in this area that makes this patent absurd.
- neilc 17y agoThe relevant prior art is not the idea of a "map" or "reduce" function as such (that isn't what is significant about MR, anyway). The patent is about parallelizing M and R operators for large-scale data analysis; I think that the relevant prior art would include 1980s work on parallel database systems (e.g. Gamma, Bubba).
