[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13402210#comment-13402210 ] 

Steven Hawkins commented on TEIID-4881:
---------------------------------------

Made a commit to change the metadata load and ddl processing to be performed sequentially after the parsing of the vdb structure.  This two phase approach keeps thing relatively consistent with the current logic.  This loosened the previous restriction on the ddl somewhat, which I'll update in the docs.  However it also means that for now metadata caching is not supported - as that was tied to the notion of metadata loading for a schema.  It also means that load will not wait for source availability or retry if there is an issue with getting a connection.  All of which make the load look more like the behavior of Teiid embedded.

> In several aspects the metadata systems are different, which is touched on in TEIID-4536
> This issue will cover making them function as similarly as possible and to also document the ways in which they are different.
