> When a query involves more columns to project than columns in index and query
> condition involves leading columns in local index then first we can get
> matching rowkeys from local index table and then get the required columns
> from data table. In local index both data region and index region co-reside
> in the same RS, we can call get on data region to get the missing columns in
> the index, without any n/w overhead. So it's efficient.
