> 1) Batch to row converter doesn't propagate columns correctly because they
> are not in the schema.
> 2) Then, even if it did, the current VrbCtx model of ACID column propagation
> only works with VectorMapOperator. Regular MapOperator has no such context;
> the reader ends up storing the vector in some fake temporary ctx. I left a
> TODO that combined with a fix to (1) could fix this instead of disabling it.
