public class TemporalProcessTimeJoinOperator
extends BaseTwoInputStreamOperatorWithStateRetention

The operator to temporal join a stream on processing time.

For temporal TableFunction join (LATERAL TemporalTableFunction(o.proctime)) and temporal table join (FOR SYSTEM_TIME AS OF), they can reuse same processing-time operator implementation, the differences between them are: (1) The temporal TableFunction join only supports single column in primary key but temporal table join supports arbitrary columns in primary key. (2) The temporal TableFunction join only supports inner join, temporal table join supports both inner join and left outer join.
