MapReduce is a programming model and processing framework for handling large-scale data sets across distributed computing clusters, popularized by Google and implemented in open-source systems like Apache Hadoop. It splits work into a 'map' phase that processes and filters data in parallel and a 'reduce' phase that aggregates the results, enabling scalable batch processing of big data.
