Index metadata should not treat cardinality 0 as unknown
--------------------------------------------------------

                 Key: TEIID-1022
                 URL: https://jira.jboss.org/jira/browse/TEIID-1022
             Project: Teiid
          Issue Type: Quality Risk
          Components: Query Engine
    Affects Versions: 6.0.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Minor
             Fix For: 7.1

The default cardinality is currently 0, which is treated as unknown, however it would be better if the default were something like -1 instead.  This will require introducing a new index file version (so that older vdbs with a value of 0 can be understood as meaning unknown) and updating the teiid/designer metadata defaults for cardinality as -1.
