             Summary: Introduce unbounded streaming inner join operator
                 Key: FLINK-12088
                 URL: https://issues.apache.org/jira/browse/FLINK-12088
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Runtime
            Reporter: Kurt Young
            Assignee: Kurt Young


This operator is responsible for unbounded streaming inner join, and will be optimized in following cases:
# If the join keys (with equality condition) are also primary key, we will have a more efficient state layout
# If the inputs have primary keys, but join keys are not primary key, we can also come up with an efficient state layout
# Inputs don't have primary keys, this will go to default implementation
