Keith Turner commented on ACCUMULO-378:
---------------------------------------
This sounds really cool. I looked at the HBase doc, it seems like it replays
the walogs on the slave cluster through the client API.
Where you thinking of doing this for all tables, or just select tables?
What are your thoughts on replicating user and table metadata in zookeeper?
What are your thoughts on enabling replication for existing data? (we clould
clone the table, copy its existing data, and replicate new walogs created after
the clone operation).
How are you thinking of handling bulk imported data? (could possible copy to
slave and bulk import on their also, this could be a FATE operation initiated
by the bulk import FATE operation).
What are your thoughts on replicating split and merge operations on the master
cluster?
I am wondering how much we can leverage FATE to make this easier and more
reliable.

> Project: Accumulo
> Issue Type: New Feature
> Reporter: Sapan Shah
> Assignee: Sapan Shah
> Priority: Minor
>
> The use case here is where people have multiple data centers and need to
> replicate the data in between them. Accumulo can model this replication
> after the way that HBase currently handles the replication as detailed here
> (http://hbase.apache.org/replication.html).
> There will be one master Cluster and multiple slave clusters. Accumulo will
> use the Master-Push model to replicate the statements from the master
> clusters WAL to the various slaves WALs.
