> Event time can not reach END_OF_GLOBAL_WINDOW in unbounded world. (Except for 
> testing)
> But Flink runner will set some timers when user set a StatefulPardo/GBK with 
> GlobalWindow. Flink maintains timers in PriorityQueue on the Java Heap. There 
> is a bad performance when the number of keys is very much.
