How Arrows collide with Tungsten and its binary in-memory format. It will still has to convert between them. I assume they use similar concepts/layout hence it is likely the conversion can be quite efficient. Or is there a change that the current Tungsten in memory format would be replaced by Arrows in the future. The same applies for Impala, Drill and all others. Is the goal to unify internal in-memory representation for all of them or the benefit is going to be in conversions faster by e.g. order of magnitude?
Many thanks for any explanation, Petr
