DESCRIPTION
This component looks up the key for a tuple in the ignore file, if specified, and ignores the tuple (passes it on as is) if it's found there, otherwise it looks it up in the cache file and if an attribute is found in cache it is associated with the tuple, otherwise, if a cache miss occurred the tuple is pushed out on the 'tuple_not_cached' port for processing by other means.
