> Improve consistency of performance during heavy load
> ----------------------------------------------------
>
> Key: HBASE-2981
> URL: https://issues.apache.org/jira/browse/HBASE-2981
> Project: HBase
> Issue Type: Brainstorming
> Components: regionserver
> Reporter: Todd Lipcon
>
> Currently when running load tests like YCSB, we experience periods of
> complete cluster inactivity while all clients are blocked on a single region
> which is unavailable.
> As discussed recently on the list, we should brainstorm some ideas for how to
> improve the situation: the goal here is to (a) minimize the amount of time
> when a region is inaccessible, and (b) minimize the impact that one
> inaccessible region has on other operations in the cluster.
