Since Pipeline and Datamanager are not tied to each other, do we want to think about the possiblity of "syncing" them. that is when i do a read currently on a pipe, i have to manually store the data, should that be automatic, this used to happen in the way begining of pipeline, but we removed it since we wanted to keep it modular Yes, I think that makes totally sense. If you it should be automatic, well, we could configure it to be or not. In the same spirit, I was thinking of some kind of storeFallback option we can pass to a pipe. If we call a read on a pipe and there is no connection, we fallback automatically on the local store to retrieve the data (with some metadata/flag saying it's local data).
