I can use split only when I am aware of the values by which I need to split by... Here customer_ids are unknown to me. I don't know how many of them exist in my data. Hence SPLIT is not the answer to my problem.
Anyways I have found piggybank's MultiStorage method much closer to what I am looking for. I was just wondering is there a better or different way to do the same.
