Best Way To Familiarize With DF

This is helpful. I'm trying to use this to retrieve all records from a table on a post post using:
$csvInfo = DreamFactory\Core\Utility\ServiceHandler::handleRequest('GET','mysql','_table/saa-recipients');
var_dump($csvInfo);

It's only returning the record I just submitted via POST and not all records. This is sort of useless as my post data is available as \Request::json()->all();
