Tables

Tables Used for Custom Mapping of XWiki Classes

The custom mappings configuration is done in the xwiki.hbm.xml file which is available on GitHub

For the moment, the "XWikiComments" class is not using the xwiki.hbm.xml custom mapping, so the xwikicomments table will be empty.

Tables Used by the Statistics Plugin

Tables Used in the Deprecated Table Class Property System

Given that now the class information is stored in the XWD_CLASS_XML column of the xwikidoc table, the tables below are not used anymore:
