I'm curious what kind of performance improvement you are seeing with the snapshot scan In my tests, I was able to get 50-60 MB/s per region, versus 10-11 MB/s for regular scans (see https://issues.apache.org/jira/browse/HBASE-8369?focusedCommentId=13805748&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13805748). Bryan, can you also share your performance numbers if you can quantify? > Backport MapReduce over snapshot files [0.94] > --------------------------------------------- > > Key: HBASE-10076 > URL: https://issues.apache.org/jira/browse/HBASE-10076 > Project: HBase > Issue Type: Bug > Reporter: Lars Hofhansl > Assignee: Jesse Yates > Fix For: 0.94.15 > > Attachments: hbase-10076-v0.patch > > > MapReduce over Snapshots would be valuable on 0.94. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
