Yeah I think a substitute comment is preferable to removal, thanks for
providing the proper definition. Per your suggestion Iâll change it to:
Base class for dependencies where each partition of the child RDD depends
on a small number of partitions of the parent RDD. Narrow dependencies allow
for pipelined execution.
