> This operator is responsible for unbounded streaming semi/anti join, and will be optimized in following cases:
> 1. If the join keys (with equality condition) are also primary key, we will have a more efficient state layout
> 2. If the inputs have primary keys, but join keys are not primary key, we can also come up with an efficient state layout
> 3. Inputs don't have primary keys, this will go to default implementation
