Improve webrequest-refine shuffle-sort
Closed, ResolvedPublic


Webrequest-refine currently shuffles both raw and augmented data to enforce rows being distinct. As augmented values are computed deterministically the distinct part can be enforced using only raw data, therefore preventing having augmented-data being shuffled between mappers and reducers (network + disk IOs reduction).
