                 Key: TEIID-1803
                 URL: https://issues.jboss.org/browse/TEIID-1803
             Project: Teiid
          Issue Type: Bug
          Components: Server
    Affects Versions: 7.4, 7.3, 7.2, 7.1.1
         Environment: JBoss Enterprise Data Services Platform 5.1.0
            Reporter: Johnathon Lee
            Assignee: Steven Hawkins


Problem:
The index metadata loading logic is not well optimized. In short, each time a call to IndexMetadataFactory.queryIndex is made the blocks are fully scanned.  For small VDBs there isn't much of an issue because of the block caching logic, but during a vdb deploy we could be constantly re-reading data from the files.

Possible solution:
The IndexMetadataFactory loading strategy should be made aware of the index file per schema strategy so that scans can be made per schema rather than against all index files.
