As per our discussion in this [thread|[https://lists.apache.org/thread.html/2529aa4fc80b1d5bbf86a7e6320aa675de05c68c84a327fe4c17d286@%3Cdev.beam.apache.org%3E]],

I am thinking to add a new rule for Join which matches when:
 * One of the input has Global Windows with Non-default Trigger.

As long as one of the input has Global Windows with Non-default Trigger, this rule should match not caring about the other input whether it is Bounded (or) not. By doing this, we will also be supporting BoundedTable JOIN [Triggered PCollectionView]
