> allow sub-range repairs (specifying -et -st) for a preview of repaired data
> ---------------------------------------------------------------------------
>
> Key: CASSANDRA-13570
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13570
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Matt Byrd
> Assignee: Matt Byrd
> Priority: Minor
> Fix For: 4.0

>
> I don't see any inherent reason for restricting preview repairs of repaired
> data to not allow specifying start and end tokens.
> The restriction seems to be coming from the fact that incremental=true in
> RepairOption, which is the case but it's not truly an incremental repair
> since we're only previewing.
> {code:java}
> if (option.isIncremental() && !option.isGlobal())
> {
> throw new IllegalArgumentException("Incremental repairs cannot be
> run against a subset of tokens or ranges");
> }
> {code}
> It would be helpful to allow this, so that operators could sequence a sweep
> over the entirety of the token-space in a more gradual fashion.
> Also it might help in examining which portions of the token-space differ.
> Can anyone see any reasons for not allowing this?
> I.e just changing the above to something like:
> {code:java}
> if (option.isIncremental() && !option.getPreviewKind().isPreview() &&
> !option.isGlobal())
> {
> throw new IllegalArgumentException("Incremental repairs cannot
> be run against a subset of tokens or ranges");
> }
> {code}
