Hello everybody, I have a use case where I need to exclude from a DataStream (that is technically a DataSet since I work in batch mode) all already-indexed documents. My idea is to perfrom an outer join but I didn't find any simple example on DataStream working on batch mode..I've tried using coGroup() but then it requires me to specify a windows strategy..in batch mode I would't expect that..can I use global window?
Thanks in advance, Flavio
