> 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
