Review comment:
The Green Team provided a presentation and recommendations for DUnit
tests that result in tests that are easy for other developers to maintain. One
important recommendation is to use the Geode User APIs directly instead of
using any sort of API replacement/wrapper including ClusterStartupRule. See
[The Green
Report](https://docs.google.com/presentation/d/13FrlS6AJQayi5Iyr_jG3c0kqwxPz-aSkEqBOHRSCj_w/edit?usp=sharing)
(if you don't have access please let me know -- I'm happy to share it with
anyone).
Basically, if a Rule or Wrapper hides anything about configuring, starting,
stopping, or doing anything with Geode then we should not use it because it
obscures Geode.

Review comment:
Our coding standard has always disallowed declaration of multiple fields
on one line. This may have slipped with Patrick setup spotless for Geode, but
there was never a group discussion on the dev-list to get rid of this style
requirement.

Review comment:
I recommend using ExecutorServiceRule for several reasons. Most
important is that it always performs tearDown (ie shutdownNow) even if the test
blows up before invoking `executorService.shutdown();`

> Parallel Disk Store Recovery when Cluster Restarts
> --------------------------------------------------
>
> Key: GEODE-8035
> URL: https://issues.apache.org/jira/browse/GEODE-8035
> Project: Geode
> Issue Type: Improvement
> Reporter: Jianxia Chen
> Assignee: Jianxia Chen
> Priority: Major
> Labels: GeodeCommons, GeodeOperationAPI
>
> Currently, when Geode cluster restarts, the disk store recovery is
> serialized. When all regions share the same disk store, the restart process
> is time consuming. To improve the performance, different regions can use
> different disk stores with different disk controllers. And adding parallel
> disk store recovery. This is expected to significantly reduce the time to
> restart Geode cluster.
