This module is EXPERIMENTAL. That means that the behaviour of these functions, these function names, in concreto ANYTHING documented here can change in a future release of this package WITHOUT NOTICE. Be warned, and use this module at your own risk.
Depending on the database you will not really get more speed compared to query() . The advantage of limitQuery() is the deleting of unneeded rows in the resultset, as early as possible. So this can decrease memory usage.
