----------------------------------
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
