> @flyrain Agree on that. With CoW, without any row-identifier, it is not possible to establish link with the new state and old state of the records without ambiguities. > > For the CDF record structure, we grokked a bit on the design and came up with [this](https://docs.google.com/document/d/14ZRQc1anvXN52HGoNpSbKy7Ua6_7IIkr6mlXe_gHrJA/edit?usp=sharing). > > Above proposal is based on our use case where we are interested in change of a certain column but also want the values of other columns. If the whole state is part of CDF record, the consumer can avoid query/lookup/join with the table to get rest of the state. > > cc - @SreeramGarlapati @rawataaryan9 @dharamshoo This design would work great for our use case, is exactly what we need.
