Class RowDataFieldsKinesisPartitionKeyGenerator

java.lang.Object

org.apache.flink.connector.kinesis.table.RowDataFieldsKinesisPartitionKeyGenerator

All Implemented Interfaces:

Serializable, java.util.function.Function<org.apache.flink.table.data.RowData,String>, PartitionKeyGenerator<org.apache.flink.table.data.RowData>

@Internal
public final class RowDataFieldsKinesisPartitionKeyGenerator
extends Object
implements PartitionKeyGenerator<org.apache.flink.table.data.RowData>

A PartitionKeyGenerator of RowData elements that constructs the partition key from a list of field names.

The key is constructed by concatenating the string representations of a list of fields projected from an input element. A fixed prefix can be optionally configured in order to speed up the key construction process.

Resulting partition key values are trimmed to the maximum length allowed by Kinesis.
