Java Rdd Reduce By Key . Reducebykey, as the name suggests, would apply a reduce operation on the javapairrdd for which the key is the same. If you refer to the. In spark, the reducebykey function is a frequently used transformation operation that performs aggregation of data. As its name implies, reducebykey() reduces data based on the lambda function you pass to it. Spark rdd reducebykey() transformation is used to merge the values of each key using an associative reduce function. Groupbykey () groups all values with the same key into a new rdd, while reducebykey () performs a reduction function on all values with the same key to produce a single reduced value. In our example, we can use reducebykey to calculate the. 106 rows return a new rdd that is reduced into numpartitions partitions. For each key k in this or other, return a resulting rdd that contains a tuple. The reducebykey operation combines the values for each key using a specified function and returns an rdd of (key, reduced value) pairs. In your example, this function is a simple.
