@Enclosing public class TemporalJoinRewriteWithUniqueKeyRule extends org.apache.calcite.plan.RelRule<TemporalJoinRewriteWithUniqueKeyRule.TemporalJoinRewriteWithUniqueKeyRuleConfig>
Planner rule that rewrites temporal join with extracted primary key, Event-time temporal table join requires primary key and row time attribute of versioned table. The versioned table could be a table source or a view only if it contains the unique key and time attribute.

Flink supports extract the primary key and row time attribute from the view if the view comes from StreamPhysicalRank node which can convert to a StreamExecDeduplicate node finally.
