DataStreamUtils

class DataStreamUtils[T] extends AnyRef

This class provides simple utility methods for collecting a DataStream, effectively enriching it with the functionality encapsulated by DataStreamUtils.

This experimental class is relocated from flink-streaming-contrib.

  14. def reinterpretAsKeyedStream[K](keySelector: (T) ⇒ K)(implicit arg0: TypeInformation[K]): KeyedStream[T, K]

    Reinterprets the given DataStream as a KeyedStream, which extracts keys with the given KeySelector.

    Reinterprets the given DataStream as a KeyedStream, which extracts keys with the given KeySelector.

    IMPORTANT: For every partition of the base stream, the keys of events in the base stream must be partitioned exactly in the same way as if it was created through a DataStream#keyBy(KeySelector).

    keySelector

    Function that defines how keys are extracted from the data stream.

    returns

    The reinterpretation of the DataStream as a KeyedStream.
