Subject [jira] Updated: (CASSANDRA-520) Implement Range Repairs
Date Fri, 06 Nov 2009 00:39:32 GMT


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.
