Description

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.
