public class WindowJoinOperator extends TableStreamOperator<org.apache.flink.table.data.RowData> implements org.apache.flink.streaming.api.operators.TwoInputStreamOperator<org.apache.flink.table.data.RowData,org.apache.flink.table.data.RowData,org.apache.flink.table.data.RowData>, org.apache.flink.streaming.api.operators.Triggerable<org.apache.flink.table.data.RowData,Long>, org.apache.flink.streaming.api.operators.KeyContext
A streaming window join operator implemented by sync state api.

Note: currently, WindowJoinOperator doesn't support early-fire and late-arrival. Thus, late elements (elements belong to emitted windows) will be simply dropped.

Note: currently, WindowJoinOperator doesn't support DELETE or UPDATE_BEFORE input row.
