Review Comment:
This should probably be more subtle. The parallelism is effectively set by
the client. In some cases and with in-proper settings that can lead to poorer
performance. So we may want to feature flag this. We may also want to add a
threshold for this, that would make smaller relations leverage the old code
path.
