Max Rydahl Andersen commented on HBX-680:
-----------------------------------------

should be possible by generating a reveng.xml file that contains the schema....or write a MetadataDialect that can do the caching ....alternatively provide a specifalized MetadataDialect that can read metadata from TeraData faster (should be possible, right ?)

> I'm currently connecting to Tera Data and reverse engineering using the Hibernate IDE.  While I have specified both the schema-selection element as well as table-filter element, my performance is still very slow (> 15 minutes with every table addition).  Is it possible to give the user the option to enable caching of the database metadata?  In the case of reverse engineering existing tables, the schema will never change or change very little, and querying the database for them vs. a local cache is very inefficient.
