> Hi
> So currently the StatefulParDoFn create timers for all the records.
> [https://github.com/apache/beam/blob/master/runners/core-java/src/main/java/org/apache/beam/runners/core/StatefulDoFnRunner.java#L211]
> This becomes a problem if you are using GlobalWindows for streaming where
> these timers get created and never get closed since the window will never
> close.
> This is a problem especially if your memory bound in rocksDB where these
> timers take up potential space and sloe the pipelines considerably.
> Was wondering that if the pipeline runs in global windows we should avoid
> adding timers to it at all?
