Subject [jira] [Commented] (ACCUMULO-378) Multi data center replication
Date Tue, 07 Feb 2012 21:16:59 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13202799#comment-13202799
] 

Keith Turner commented on ACCUMULO-378:
---------------------------------------

Replicating table configuration would be useful.  For example if a user enables an age off
iterator on the master cluster for major compaction, it would be nice to have that run on
the slave cluster and throw old data away.  Would want the same iterators configured for the
master and slave table, compression, locality groups, etc.  Wonder if we could leverage ZOOKEEPER-892.

> 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.
