> Instead of configuring a fixed size number of threads (maxConcurrency and 
> targetConcurrency), @larsh had a good idea to specify it as a percentage of 
> available server-side resources. So the number of chunks to split up a scan 
> and run them in parallel would become:
>       parallelizationFactor * numberOfRegionServers
> We could potentially do even better by returning in our compatibility checker 
> (that runs once at init time per cluster) the number of handler threads for 
> each region server. Then we'd have a more accurate number of total available 
> resources.
