VDB deployment in EDS can be extremely slow based upon indexing needs
---------------------------------------------------------------------
Key: TEIID-1804
URL: https://issues.jboss.org/browse/TEIID-1804
Project: Teiid
Issue Type: Bug
Components: Server
Affects Versions: 7.1.1, 7.2, 7.3, 7.4
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.
