The following is a typical graphical representation of the MapReduce pattern. The input goes through various mapped functions, with each returning a set of mapped values as output. These are then grouped and joined by Reduce() functions to create the final output:
Follow these steps to implement the MapReduce pattern using LINQ:
- First, we need to write a map function with a single input value that returns a set of mapped values. We can use LINQ's SelectMany function for this.
- Then, we need to group data according to the intermediate key. We can use LINQ's GroupBy method for this.
- Finally, we need a reduce ...
