Re: big table / hadoop / map reduce

Hi Artur, Here is an article on wikipedia: http://en.wikipedia.org/wiki/MapReduce And here are the native implementations in php: http://www.php.net/manual/en/function.array-map.php http://www.php.net/manual/en/function.array-reduce.php The basic idea is to gather a lot of data, from several nodes, and "map" them togheter; then, assuming a lot of this data is repeated across the dataset, we "reduce" them. Cheers.
