did anyone work on creating json files dynamically from flat files/database? I know I can use twritejson or data mapper. if I use these components, then i have to write job for each file. I am looking for metadata driven. it means i want to use the same code to generate files. i just give input and output structures. it should automatically create the output json files. I think this can be achieved by java or python core programming. but, i want to check if there is a component that takes care of it.
