Paul Nittel closed TEIID-1742.
------------------------------
I'm taking Steve's word for this. I don't have the time to run any test 2^32
(or 4,294,967,296) times.
Closed.
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
Priority: Blocker
Fix For: 7.4.1, 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.)
