> The "continuation trigger" for a processing time trigger is a synchronized processing
time trigger. Today, this throws an exception in the FlinkRunner.
> The supports the following:
>  - GBK1
>  - GBK2
> When GBK1 fires due to processing time past the first element in the pane and that element
arrives at GBK2, it will wait until all the other upstream keys have also processed and emitted
corresponding data.
> Sorry for the terseness of explanation - writing quickly so I don't forget.
