table
is
t
, then the
action
applies to all tables. If
table
is
:default
, then the default caching action is set for those tables which do not have an explicit setting.
database specifies the database connection, its default value is the value of *default-database*.

, the setting applies to all tables which do not have an explicit setup.
The value

means remove any existing cache for
table
in

, but continue to cache.
