Duo Zhang commented on HBASE-25283:
-----------------------------------
If HBASE-26233 could be done then we do not need to fix this issue any more, as
we do not rely on the general replication framework in HBASE-26233, so we do
not need the RegionReplicaReplicationEndpoint any more, thus we do not need to
polish it too.
Will report back once HBASE-26233 is finished.
Thanks.

> I do not like that we have a specialized implementation for meta replica
> inside the region replica framework. They are almost the same so they should
> share the same code base. I think this enhancement could also be applied to
> normal RegionReplicaReplicationEndpoint, what we need is the config for the
> max distance between different secondary replicas. For normal region
> replicas, the value will be small, which means we will soon block the
> replication if any replicas are slow, to save memory. For meta replicas, we
> could have a large default value to let the good replicas catch up fast.

> Lets use this issue to fill out more on what [~zhangduo] suggests above.
