Will Berkeley reassigned KUDU-2056:
-----------------------------------
Assignee: Will Berkeley
> Expose a metric for how much a tablet needs to be compacted
> -----------------------------------------------------------
>
> Key: KUDU-2056
> URL: https://issues.apache.org/jira/browse/KUDU-2056
> Project: Kudu
> Issue Type: Improvement
> Components: tablet
> Reporter: Jean-Daniel Cryans
> Assignee: Will Berkeley
> Priority: Major
>
> Now that the maintenance manager is fast at scheduling tasks, I've seen
> clusters running 1.4 that are churning through compactions at a high rate
> with seemingly no end in sight. At least it *feels* like it, but there's no
> easy way to verify.
> I think it would be good to have some measure of how "uncompacted" a tablet
> is. Todd thinks we could just use the average "height" of what's seen on the
> "Rowset Layout Diagram" page.
