Rdd.reducebykey . the `reducebykey ()` method is a transformation operation used on pair rdds (resilient distributed datasets. reducebykey uses that property to compute a result out of an rdd, which is a distributed collection consisting of partitions. spark rdd reducebykey () transformation is used to merge the values of each key using an associative reduce function. the reducebykey operation combines the values for each key using a specified function and returns an rdd of (key, reduced value) pairs. In our example, we can use reducebykey to calculate the total sales for each product as below:
