hi, guys. I want to know the differance between this PR and
https://github.com/apache/flink/pull/3386
You have 138 comments, but now rewrite the FLINK-3386. Why not recommend this
solution at 3386. Do we must waste of time on the same problem?

> 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.
