> Apache Arrow have added View types in 1.4 of the spec. The arrow-java version
> in use in spark already has support for them. Modern data systems might
> choose to produce those arrow types instead of usual List/Utf8/Binary types
> since they support random reads and writes without having to reallocate whole
> vector. Spark should support reading those vectors in its columnar execution
