Package org.apache.flink.streaming.api.operators.sortpartition

Class VariableLengthByteKeyAndValueComparator<INPUT>

  • All Implemented Interfaces:
    Serializable
    @Internal
public class VariableLengthByteKeyAndValueComparator<INPUT>
extends org.apache.flink.api.common.typeutils.TypeComparator<org.apache.flink.api.java.tuple.Tuple2<byte[],​INPUT>>
    The VariableLengthByteKeyAndValueComparator is used by KeyedSortPartitionOperator to compare records according to both the record key and record value. The length of record key must be variable and will be read from DataInputView.
