Van Halbert commented on TEIID-4977:
------------------------------------

There appears to be an issue with the registering of descriptors, getting this error:

> Need to enable the materialization process to load the cache "offline" and not impact access to current cache and data.   This would be similar to how the 8.12.x version was implemented and similar to how RDBMS materialization is done.
