So for > example, if a table has 10 regions with replication = 3, the table would > indeed be created with 30 regions. These regions will be handled and assigned > individually for AM purposes. > We can add replicaId to HRegionInfo to indicate the replicaId, and use this > to differentiate different replicas of the same region. So, primary replica > would have replicaId = 0, and the others will have replicaId > 0. > These replicas will share the same regionId prefix, but differ in an appended > replicaId. The primary will not contain the replicaId so that no changes > would be needed for existing tables. > In meta, the replica regions are kept in the same row as the primary ( so for > above example, there will be 10 rows in meta). The servers for the replicas > are kept in columns like "server+replicaId". -- This message was sent by Atlassian JIRA (v6.1.5#6160)
