Subject [jira] Commented: (CASSANDRA-520) Implement Range Repairs
Date Wed, 04 Nov 2009 17:37:32 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12773578#action_12773578
] 

Stu Hood commented on CASSANDRA-520:
------------------------------------

One straightforward way to implement the repair would be to perform a range read for each
disagreeing range, and letting read repairs handle repairing individual keys. This would require
a command similar/identical to RangeCommand except that it would use Tokens as the 'startWith'
and 'stopAt' parameters.

> After CASSANDRA-193, the TreeRequest/Response conversation will have generated a full
list of Ranges that disagree between nodes. We need an operation that can efficiently batch
repair the ranges, similar to what happens during read repair for a single key.
