> Currently, there is no good way to tune the replica lag configs to
> automatically account for high and low volume topics on the same cluster.
> For the low-volume topic it will take a very long time to detect a lagging
> replica, and for the high-volume topic it will have false-positives.
> One approach to making this easier would be to have the configuration
> be something like replica.lag.max.ms and translate this into a number
> of messages dynamically based on the throughput of the partition.
