Subject [jira] [Created] (CASSANDRA-5220) Repair improvements when using vnodes
Date Mon, 04 Feb 2013 23:14:13 GMT
Brandon Williams created CASSANDRA-5220:

             Summary: Repair improvements when using vnodes
                 Key: CASSANDRA-5220
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.2.0 beta 1
            Reporter: Brandon Williams
            Assignee: Yuki Morishita
             Fix For: 1.2.2

Currently when using vnodes, repair takes much longer to complete than without them.  This
appears at least in part because it's using a session per range and processing them sequentially.
 This generates a lot of log spam with vnodes, and while being gentler and lighter on hard
disk deployments, ssd-based deployments would often prefer that repair be as fast as possible.
