> 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.
