caching - How to clear zend metadata cache using tags -

i'm using redis cache backend, clean metadata cache - there kind of default tag(s) zend metadatas remove cache without flushing data?

components such zend_db_table_abstract don't use tags save objects cache, believe trying clean cache the empty tag should it:

$cache->clean(   zend_cache::cleaning_mode_matching_any_tag,   array('') );
