> For the use of flink on k8s, for performance considerations, it is important
> to choose a CNI plug-in. Usually we have two environments: Managed and
> UnManaged.
> Managed: Cloud vendors usually provide very efficient CNI plug-ins, we
> don’t need to care about network performance issues
> UnManaged: On self-built K8s clusters, CNI plug-ins are usually optional,
> similar to Flannel and Calcico, but such software network cards usually lose
> some performance or require some additional network strategies.
> For an unmanaged environment, if we also want to achieve the best network
> performance, should we support the *HostNetWork* model?
> Use the host network to achieve the best performance
