Which tech for measures on HDP?
When using HDP techs to provide a star schema, which tech is the right one to use for traditional edw measures? I’m thinking calculated columns or measures in the MDX/DAX world of comparable Microsoft techs. I get that with tools like impala or hive if I’ve got a fact table with dimension keys I can do a typical group by on dimension attributes and do simple aggregation funcs (e.g. sum/avg etc.) But if I want to store standard business calculations that the business has agreed upon, what are some approaches for surfacing these so everyone who wants to consume the facts doesn’t have to rewrite complex calculation queries?
Thanks in advance.
