@hombit My explanation comes more from an IO-bound workload. If there is a valid CPU-bound use case, I think it is fine to add this as an improvement. So the implication is that we require thread-safety across different columns readers if this PR gets merged. For example, a custom ArrowInputStream implementation that supports I/O prefetching now needs to consider the new pattern. -- This is an automated message from the Apache Git Service.
