Feldera tries to be row- and column-oriented in the respective parts that matter. E.g. our LSM trees only store the set of columns that are needed, and we need to be able to pick up individual rows from within those columns for the different operators.
I don't think we've converged on the best design yet here though. We're constantly experimenting with different layouts to see what performs best based on customer workloads.
