Class PrintSinkFunction<IN>

  • Type Parameters:
    IN - Input record type
    All Implemented Interfaces:
    Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, org.apache.flink.api.common.SupportsConcurrentExecutionAttempts, SinkFunction<IN>

public class PrintSinkFunction<IN>
extends RichSinkFunction<IN>
implements org.apache.flink.api.common.SupportsConcurrentExecutionAttempts

    This interface will be removed in future versions. Use the new PrintSink interface instead.
    Implementation of the SinkFunction writing every tuple to the standard output or standard error stream.

    Four possible format options: sinkIdentifier:taskId> output <- sinkIdentifier provided, parallelism > 1 sinkIdentifier> output <- sinkIdentifier provided, parallelism == 1 taskId> output <- no sinkIdentifier provided, parallelism > 1 output <- no sinkIdentifier provided, parallelism == 1
