In Custom Translator, Is it possible to change metadata content ? For example by extending the BaseDelegatingExecutionFactory ? Are through any other custom translator method exist to modify metadata ? By developing custom translator is it possible to return any table structure by this way ?
Yes, you can. If MetadataRepository is generic for type of source, translator is more specific to a give source type. But note that even translator only lists metadata at deployment time of vdb not when you want.
