> 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.
