> Currently `event time OVER ROWS BETWEEN UNBOUNDED PRECEDING aggregation to 
> SQL`  implementation  class: ` UnboundedEventTimeOverProcessFunction` use 
> data size uncontrollable memory data structures`sortedTimestamps: 
> util.LinkedList [Long] cache data timestamps and sort timestamps. IMO,It's 
> not a good way, because in the production environment there are millions of 
> window data pre millisecond in our application scenario.So, I want to remove 
> `util.LinkedList [Long] `. Welcome anyone to give me feedback.
> What do you think? [~fhueske] and [~Yuhong_kyo]
> When a SortedQueueState is available,we will Update all OVER window 
> ProcessFunction implementations to use the SortedQueueState.
