Google’s MapReduce: Revolutionizing Big Data Processing
The concept of MapReduce, developed by Google, has revolutionized the way big data is processed. Using this concept, Google created an open-source software called MapReduce, which is based on the notion of dividing data into smaller chunks and processing them in parallel.
But what exactly is MapReduce? It is a programming model and an associated implementation. Derived from the mapping and reducing functions in functional programming, MapReduce was developed by Google to handle large-scale data processing tasks.
The concept behind MapReduce is to divide a big data set into smaller, manageable pieces, which are then processed independently on different machines or nodes. The data is divided into key-value pairs, where the key represents a unique identifier and the value represents the corresponding data. Each pair is then passed through a mapping function to create a set of intermediate key-value pairs.
The intermediate key-value pairs are then grouped by key and passed through a reducing function to produce a final set of key-value pairs. This process allows for distributed and efficient processing of large amounts of data, as it can be performed in parallel on multiple machines.
