Subject [jira] [Created] (ACCUMULO-3648) Ability to Scan Table Keys in Reverse Order
Date Thu, 05 Mar 2015 20:52:38 GMT
Mike Fagan created ACCUMULO-3648:

             Summary: Ability to Scan Table Keys in Reverse Order
                 Key: ACCUMULO-3648
             Project: Accumulo
          Issue Type: Improvement
          Components: master, tserver
            Reporter: Mike Fagan
            Priority: Minor

There are cases where you would like to scan a table in reverse key order.

For example: 
Consider a table using an inverted timestamp key.
This allows for very quick access to the latest records.

But  It would be helpful to quickly access earliest records without having to:
A) scan through all the records to build a collection to reverse sort
B) store the table again using the reverse key
