Subject [jira] [Commented] (ACCUMULO-378) Multi data center replication
Date Wed, 16 Oct 2013 22:08:43 GMT


Josh Elser commented on ACCUMULO-378:

[~kturner], [~sapanbshah42], did you guys ever come up with any sort of design document? Looking
back at the last chatter, we were still in a localfs WAL capability which is a bit out of
date considering current Accumulo support :)

Given [~rmutyala]'s question on dev@a.a.o about this, any interest in thinking about this
as a major 1.7 feature? It will give something to think about while testing 1.6.0 :)

> 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 (  
> 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.
