Subject Data Types for Item/Element Ids
Date Fri, 09 Jul 2010 10:04:21 GMT
Hi everyone,

In mahout, I get the impression that most of the data structures require
item/element ids to be longs or ints.  As Mahout is designed to scale up to
huge data sets, would it be useful to also allow strings as ids, such as
universally unique identifiers?  Any comments?
