[teiid-issues] [JBoss JIRA] (TEIID-1022) Index metadata should not treat cardinality 0 as unknown

[Steven Hawkins (Resolved) (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-1022?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-1022.
-----------------------------------

    Resolution: Done


Updated the indexing and metadata logic so that -1 is a proper default throughout.  Also cloned to a designer issue for resolution there.

> 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.
