Origin of mapreduce
Witryna2 cze 2024 · MapReduce is a processing module in the Apache Hadoop project. Hadoop is a platform built to tackle big data using a network of computers to store and process data. What is so attractive about Hadoop is that affordable dedicated servers are enough to run a cluster. The name MapReduce originally referred to the proprietary Googletechnology, but has since been genericized. By 2014, Google was no longer using MapReduce as their primary big dataprocessing model,[12]and development on Apache Mahouthad moved on to more capable and less disk-oriented … Zobacz więcej MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel, distributed algorithm on a cluster.
