org.apache.flink.table.runtime.typeutils.serializers.python.RowDataSerializer

All Implemented Interfaces:

Serializable

@Internal
public class RowDataSerializer
extends org.apache.flink.table.runtime.typeutils.RowDataSerializer

A TypeSerializer for RowData. It should be noted that the row kind will be encoded as the first 2 bits instead of the first byte. Currently Python doesn't support RowData natively, so we can't use RowDataSerializer in blink directly.
