Subject [jira] Commented: (HBASE-2197) Start replication from a point in time
Date Wed, 10 Feb 2010 02:18:28 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2197?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12831823#action_12831823

ryan rawson commented on HBASE-2197:

I am not generally a fan of depending on files and region layout.  We need to have a system
where we can bring up a cluster immediately and get new edits in then pull in the rest of
them as fast as possible.  I think the latter process should be out of bounds, ie: lets keep
the replication core in HRS really small, then add value on and around it, possibly with some
HRS hooks if necessary.

As for the random read issue, we should highly consider removing that code.

We need a way to make sure we don't miss any edits by being able to start a process that reads
old log files from a defined point in time and send them to a specific slave cluster and then
catch up with normal replication.
