the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.

> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Network
> Reporter: Garrett Li
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> A logical network connection exists for each point-to-point exchange of data
> over the network, which typically happens at repartitioning- or broadcasting
> steps (shuffle phase). et
> Currently Flink divide the network buffer pool evenly for every partition
> operators. Sometimes it could waste too many network buffers since we might
> have a lot of repartitioning and broadcasting in the one Flink job, and NOT
> all of the partition operators in the same job have the same traffic.
