> Now that we have the capability to run queries against table snapshots 
> through our map reduce integration, we can utilize this capability for stats 
> collection too. This would make our stats collection more resilient, resource 
> aware and less resource intensive. The bulk of the plumbing is already in 
> place. We would need to make sure that the integration doesn't barf when the 
> query is an UPDATE STATISTICS command.
