Subject [jira] Updated: (CASSANDRA-520) Implement Range Repairs
Date Mon, 07 Dec 2009 21:44:18 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-520?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stu Hood updated CASSANDRA-520:
-------------------------------

    Attachment: 520-bulk-2-repair-strategy-by-fraction.diff
                520-bulk-1-use-streaming-api.diff

Rebased to apply to trunk.

Triggering RangeCommand based repairs is a FIXME at AntiEntropyService:617, which means that
this patch won't actually trigger repairs for differences of less than 5% between nodes.

> 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.
