> It is difficult for Dataflow users to understand how modifying a pipeline or data set can affect how much inter-transform IO is used in their job. The intent of this feature request is to help users understand how side inputs behave when they are consumed.
> This will allow users to understand how much time and how much data their pipeline uses to read/write to inter-transform IO. Users will also be able to modify their pipelines and understand how their changes affect these IO metrics.
> For further information, please review the internal Google doc go/insights-transform-io-design-doc.
