I'd been using Pentaho Data Integration Community edition for over 2 years. For the past 2 days I'd been trying to develop a new step in kettle. I would like to start with something simple step say, random number generator(I know it is already available). I didn't find out a way to develop a step. Is it even possible? If so, could someone please give me some pointers where I can find examples which are simple enough to understand. Any suggestion will be greatly appreciated.
