Every section in this article is a mistake.
For instance
- Map Reduce was not invented in 2004. it's a technique from the punch card days.
- Map reduce is not solely useful because it allows you to delete source data, it's a trivial method of parallel processing. It's not the most trivial or most modern. Just common
- chrisseaton 5y agoBut they say ‘MapReduce’, not ‘map reduce’. They’re talking about the specific model, not the general idea of map reduce.
- dekhn 5y agoReally, they should be calling it "Distributed MapShuffleReduce", I let Sanjay and Jeff know this (in person) but they didn't really seem to care. Neither map nor reduce is a method of parallel processing, the shuffle stage is.
