Ramesh Reddy commented on TEIID-1580:
-------------------------------------

I do not think I quite understand what you are suggesting. Even if we move the code that is pulling the metadata from sources into the 'DynamicVDBDeployer', during the parse process, we still need to issue the individual loads into separate threads for Async processing, even in that situation MetadataStoreGroup will not be fully populated, so we will still have the same issue.

Simple case would be synchronizing the list in the MetadataStoreGroup, or avoid the update call in CompositeVDB until all the MetadataStores are available for that Dynamic VDB.
