> Project: Flink

> Priority: Not a Priority
> Labels: auto-deprioritized-major, auto-deprioritized-minor
>
> in current flink implement automatic flow control by back pressure, it is
> efficient for the most scene, but in some special scenario, do we need
> fine-grained flow control to avoid impact on other systems? For example: if i
> have window with days(a lot of datas), then do call ProcessWindowFunction
> when trigger, this will produce a lot of data to sink, if sink to message
> queue, it can have a huge impact to message queue. so if there is sink rate
> limiter, it is friendly to external system. for source rate limiter, it is
> appropriate for having window operator and accumulating a large amount of
> historical data.
