---------------------------------------------------------------------

Im about ready to run through this and put it into an initial committable 
state. I will do some quick cleanup, add some initial javadoc, write up some 
overview/QuickStart doc and it should be reasonable to start building out.

It’s often a decent experience, but doing things at scale can be a bit 
annoying. I’ve had success, but also, even with plenty of available cpu and ram 
I’ve had collection creation fail. I’ve had ZooKeeper bomb out and start 
failing updates a mile a minute. Ive seen a couple failures from the state 
update code. Familiar enough, though still inconvenient. Other than that, it’s 
a reasonable experience. I have laundry list of additional items I’ll tackle 
going forward in terms of making it easier to roll out what a dev might be 
looking for without having to sweat a lot for it.

> I’ve spent a fair amount of time over the years on work around integrating 
> Lucene’s benchmark framework into Solr and while I’ve used this with 
> additional local work off and on, JMH has become somewhat of a standard for 
> micro benchmarks on the JVM. I have some work that provides an initial 
> integration, allowing for more targeted micro benchmarks as well as more 
> integration type benchmarking using JettySolrRunner.
