Constructors in org.apache.flink.datastream.impl.stream with parameters of type AbstractDataStream

Constructor and Description
KeyedPartitionStreamImpl(AbstractDataStream<V> dataStream, org.apache.flink.api.java.functions.KeySelector<V,K> keySelector)
KeyedPartitionStreamImpl(AbstractDataStream<V> dataStream, org.apache.flink.api.java.functions.KeySelector<V,K> keySelector, org.apache.flink.api.common.typeinfo.TypeInformation<K> keyType)
KeyedPartitionStreamImpl(AbstractDataStream<V> dataStream, org.apache.flink.api.dag.Transformation<V> partitionTransformation, org.apache.flink.api.java.functions.KeySelector<V,K> keySelector, org.apache.flink.api.common.typeinfo.TypeInformation<K> keyType) This can construct a keyed stream directly without partitionTransformation to avoid shuffle.
