> Based on what is currently available in the TableAccessInfo we can infer when it would
be a good idea to add bucketing/sorting metadata for tables.  However, we can't easily tell
if we're already getting the benefits of bucketing/sorting.
> This information can be improved by
> a) storing the input table/partition objects so that we can tell if the tables/partitions
are already bucketed/sorted
> b) running the TableAccessAnalyzer after the logical optimizer, so that we can tell from
the operators whether or not we are already getting benefits (bucketed/sort merge map joins
or map group bys)
