Examples of com.hazelcast.mapreduce.ReducerFactory

com.hazelcast.mapreduce.ReducerFactory
A ReducerFactory implementation is used to build {@link Reducer} instances per key.
An implementation needs to be serializable by Hazelcast since it might be distributed inside the cluster to do parallel calculations of reducing step. @param < KeyIn> key type of the resulting keys @param < ValueIn> value type of the incoming values @param < ValueOut> value type of the reduced values @since 3.2
