    If you are doing data processing in pandas CoW allows to avoid of a lot of redundant computations on intermediate steps. Before CoW any data processing in Pandas required manual and careful working with code to avoid the case described in the blog post. To be honest I cannot imagine the case of offloading each result of each operation in the pipeline to the storage…

      So you would be using CoW in-memory in this case?

        If I already use Pandas for processing my data in-memory, CoW can significantly improve the performance. That was my point.
