> Project: Apache Arrow
> Issue Type: Improvement

> While looking at some basic instrumentation, I noticed SourceNode calls
> InputReceived directly in its Loop handler, meaning that we only ever process
> one batch at a time (barring a pipeline breaker). We should instead submit
> batches in parallel.
