> Improve diagnosability of performance problems

> Key: KUDU-1410
> URL: https://issues.apache.org/jira/browse/KUDU-1410
> Project: Kudu
> Issue Type: Bug
> Components: supportability
> Affects Versions: 0.8.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
>
> Although Kudu has been relatively stable for most users, we are starting to
> see more and more questions about performance. In internal test clusters
> we're also struggling to understand performance issues or timeouts in some
> cases from logs only, and it can require gathering a daemon trace to see
> what's going on.
> This is an umbrella ticket for various improvements we can make so that
> performance is easier to understand.
