> Currently most consuming sink node implementations require the schema so they
> can convert from ExecBatch to RecordBatch. However, the node already knows
> the schema of the batches (it is the output schema of the input). By passing
> this schema to the consumers we can avoid having to know the schema ahead of
> time and simplify creating a sink node consumer.
