[jira] Updated: (CASSANDRA-520) Implement Range Repairs
[ https://issues.apache.org/jira/browse/CASSANDRA-520?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stu Hood updated CASSANDRA-520:
-------------------------------
Attachment: 520-tokens-for-range-command.diff
This patch changes RangeCommand to take a DecoratedKey for startWith and stopAt. The idea is that a RangeCommand for a Token Range would provide DecoratedKeys with null keys. Along with 344, this allows for a naive implementation of range repairs.

> 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.
