> When we disable a peer for a time of period, and then enable it, the
> ReplicationSource in master cluster will push the accumulated hlog entries
> during the disabled interval to the re-enabled peer cluster at full speed.
> If the bandwidth of the two clusters is shared by different applications, the
> push at full speed for replication can use all the bandwidth and severely
> influence other applications.
> Though there are two config replication.source.size.capacity and
> replication.source.nb.capacity to tweak the batch size each time a push
> delivers, but if decrease these two configs, the number of pushes increase,
> and all these pushes proceed continuously without pause. And no obvious help
> for the bandwidth throttling.
> From bandwidth-sharing and push-speed perspective, it's more reasonable to
> provide a bandwidth up limit for each peer push channel, and within that
> limit, peer can choose a big batch size for each push for bandwidth
> efficiency.
> Any opinion?
