Steven Hawkins resolved TEIID-1803.
-----------------------------------
Labels: (was: teiid)
Fix Version/s: 7.6
Resolution: Done
Changed the index loading logic to perform only a single scan over the index files, then
build the metadata in memory.
VDB deployment in EDS can be extremely slow based upon indexing
needs
---------------------------------------------------------------------
Key: TEIID-1803
URL:
https://issues.jboss.org/browse/TEIID-1803
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
Fix For: 7.6
Attachments: IndexMetadata.patch.txt
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.
