      Description

      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.
