Subject [jira] [Created] (CASSANDRA-2710) Get multiple column ranges
Date Thu, 26 May 2011 10:19:47 GMT
Get multiple column ranges

                 Key: CASSANDRA-2710
             Project: Cassandra
          Issue Type: Improvement
            Reporter: David Boxenhorn

I have replaced all my super column families with regular column families using composite
columns. I have easily been able to support all previous functionality (I don't need range
delete) except for one thing: getting multiple super columns with a single access. For this,
I would need to get multiple ranges. (I can get multiple columns, or a single range, but not
multiple ranges.) 

For example, I used to have


and I could get superColumnName1, superColumnName2

Now I have


and I need to get superColumnName1..superColumnName1+, superColumnName2..superColumnName2+

to get the same functionality

I would like the clients to support this functionality, e.g. Hector to have .setRages parallel
to .setColumnNames 

and for CQL to support a syntax like 

SELECT [FIRST N] [REVERSED] name1..nameN1, name2..nameN2... FROM ...
