The tryRemoveKeyEntryDeferred method of the Dictionary class attempts to remove the (key, value) pair specified in the keys and value parameters from the external key dictionary if it is present. For persistent dictionaries, the attempt is queued and executed when the database transaction commits. For transient dictionaries, the attempt is executed immediately.

This method returns true if the dictionary is persistent or the dictionary is transient and the (key, value) pair was removed; otherwise it returns false.
