[teiid-issues] [JBoss JIRA] (TEIID-2527) Dynamically change the sources in a multi-source model

Tue Jun 25 16:12:20 EDT 2013

    [ https://issues.jboss.org/browse/TEIID-2527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12784506#comment-12784506 ] 

Steven Hawkins commented on TEIID-2527:
---------------------------------------

It looks like it will simplify the engine mechanics if the multi-source logic were effectively handled at processing time (which would also reduce the size of the cached plan).  However there would be an increase in the overhead of recreating all of the multi-source modifications (mostly command cloning).

> As a step toward a more dynamic VDB, it would be useful to allow data sources to be dynamically added/removed from a multi-source model.  For more, see https://community.jboss.org/message/821113
