Page ids are not sufficiently unique
------------------------------------
Key: TEIID-1743
URL: https://issues.jboss.org/browse/TEIID-1743
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 7.1
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Blocker
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.)
