@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 directly.
