Page ids are not sufficiently unique
------------------------------------

                 Key: TEIID-1742
                 URL: https://issues.jboss.org/browse/TEIID-1742
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.1
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 7.6

The pages used for internal matviews / temporary tables currently use a single shared integer for id generation.  Conflicts are possible then after 2^32 page allocations that access the buffermanager.

In practice this condition should take a minimum of several weeks to trigger, but more likely it would take months if not years (fewer updates, larger page sizes, less chance of an id conflict, etc.)
