public class AsyncStateWindowJoinOperator
extends AsyncStateTableStreamOperator<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 AsyncStateWindowJoinOperator implemented by async state api.

This class is nearly identical with WindowJoinOperator, but extending from AbstractAsyncStateStreamOperator to integrate with asynchronous state access.

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

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