icon Google's MapReduce patent21.01.2010. u 14:13 - pre 172 meseci
"Two years ago, David DeWitt and Michael Stonebraker deemed MapReduce a major step backwards (here are the original paper and a defense of it) that 'represents a specific implementation of well known techniques developed nearly 25 years ago.' A year later, the pair teamed up with other academics and eBay to slam MapReduce again. But the very public complaints didn't stop Google from demanding a patent for MapReduce; nor did it stop the USPTO from granting Google's request (after four rejections). On Tuesday, the USPTO issued U.S. Patent No. 7,650,331 to Google for inventing Efficient Large-Scale Data Processing."

The USPTO awarded search giant Google a software method patent that covers the principle of distributed MapReduce, a strategy for parallel processing that is used by the search giant. If Google chooses to aggressively enforce the patent, it could have significant implications for some open source software projects that use the technique, including the Apache Foundation's popular Hadoop software framework.
