---------------------------------
Summary: The region replication framework should not built upon
the general replication framework
Key: HBASE-26233
URL: https://issues.apache.org/jira/browse/HBASE-26233
Project: HBase
Issue Type: Sub-task
Reporter: Duo Zhang
At least, at the source path, where we track the edits, we should not make
region replication rely on general replication framework.
The difficulty here for switching to a table based storage is that, the WAL
system and replication system highly depend on each other. There will be cyclic
dependency if we want to store replication peer and queue data in a hbase table.
And after HBASE-18070, even meta wal provider will be integrated together with
replication system, which makes things more difficult.
But in general, for region replication, it is not a big deal to lose some
edits, a flush can fix everything, which means we do not so heavy tracking
system in the general replication system.
We should find a more light-weighted way to do region replication.
