java.lang.Object
org.apache.flink.api.common.typeutils.TypeComparator<org.apache.flink.api.java.tuple.Tuple2<byte[],INPUT>>
org.apache.flink.streaming.api.operators.sortpartition.FixedLengthByteKeyAndValueComparator<INPUT>
All Implemented Interfaces:
Serializable
@Internal public class FixedLengthByteKeyAndValueComparator<INPUT> extends org.apache.flink.api.common.typeutils.TypeComparator<org.apache.flink.api.java.tuple.Tuple2<byte[],INPUT>>
The FixedLengthByteKeyAndValueComparator is used by KeyedSortPartitionOperator to compare records according to both the record key and record value. The length of record key must be fixed and will be initialized when the FixedLengthByteKeyAndValueComparator is created.
