-------------------------------------
Summary: Undo meta replica specialization inside of the region
replica framework
Key: HBASE-25283
URL: https://issues.apache.org/jira/browse/HBASE-25283
Project: HBase
Issue Type: Improvement
Components: read replicas
Reporter: Michael Stack
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.
