Subject [jira] Created: (HBASE-786) Subclass of TableMap which accepts a date range to be applied to timestamps
Date Tue, 29 Jul 2008 21:27:31 GMT
Subclass of TableMap which accepts a date range to be applied to timestamps
---------------------------------------------------------------------------

                 Key: HBASE-786
                 URL: https://issues.apache.org/jira/browse/HBASE-786
             Project: Hadoop HBase
          Issue Type: New Feature
            Reporter: Adam Gerber
            Priority: Minor


There would exist a TableMap subclass which load only those records whose timestamp is within
the specified range.

The date range could be accessible via the initJob method, which would accept start date and
end date as parameters.
If either parameter is null, the range could be considered unbounded in that direction.

Such a class could either receive each "version" as a different input, or it could receive
arrays of those "versions" as input - 
perhaps two classes would exist, covering both approaches.

Keeping versions together could be helpful in saving the designer from having to reconstitute
this structure (to answer questions
such as "how many versions does the average record have?")
