Subject [jira] [Commented] (ACCUMULO-2574) Define storage data structure for data that needs replication
Date Fri, 28 Mar 2014 02:33:15 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13950294#comment-13950294

Josh Elser commented on ACCUMULO-2574:
--------------------------------------

This data structure should also likely support some sort of enum to differentiate whether
the file is an RFile or a WAL. Perhaps this could be handled at the thrift layer?

> We need to track data that needs replication. At a minimum we need to track where the
data came from (to support cycles in the replication graph), optional offsets into the file
that needs replicating (important for WALs to avoid having to wait for a WAL to be closed
before replicating).
> It might make sense to include where the data should be replicated to. Not sure if it
makes sense to do that as late as possible or earlier on.
