Description

Now that Phase 1 of parent issue HBASE-10070 is mostly done, it is time to think about remaining items in Phase 2 as per the design doc https://issues.apache.org/jira/secure/attachment/12616659/HighAvailabilityDesignforreadsApachedoc.pdf

Phase 2 will conclude the work and include at least the following major features:

• Async WAL Replication
• Replication Interface changes (HBASE-10504)
• Replication should guarantee seqId order (for region moves and RS failure)
• Flush / Compaction events should be written to WAL
• Flush / Memstore handling from secondary regions
• Region split / merge handling for replicated regions

In this issue, we can discuss the proposed design, and keep it as like a parent jira for Phase 2 work. We'll open subtasks agains the HBASE-10070 jira for individual patches.
