Duo Zhang commented on HBASE-25283:
-----------------------------------
Looking at the code, I think first we need to remove bunch of old (implicit)
designs in the code. Such as how we retry, and the meaning of return true for
ReplicationEndpoint.replicate method.
> Undo meta replica specialization inside of the region replica framework

> Project: HBase
> Issue Type: Improvement
> Components: read replicas
> Reporter: Michael Stack
> Priority: Major

> Filing an issue to capture a [~zhangduo] suggestion made in PR that was then
> carried to a comment over in the design document attached to HBASE-18070 only
> it is deserving of its own issue.

> 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.
