When the JADE client terminates and there were additions to the collected RootSchema class and type definitions, a persistent file of those RootSchema definitions is written into the temp directory of the JADE install directory. The file is named JadeAutoCompleteCache.jac.
When JADE is next initiated and AutoComplete is set up in an editor, that file is read and loaded. This process eliminates the need to re-retrieve those RootSchema entities from the database.
The file has the JADE version embedded in it, and if the version does not match the version of the current executable, the file is discarded.
