…ay-project#42930) To make informed scheduling decisions, Ray Data estimates the object store memory usage from each operator. Currently, an operator's inputs count towards its memory usage; however, this can lead to suboptimal scheduling decisions since we primarily care about outputs for backpressuring. This PR updates the implementation so that input counts toward the previous operator's object store usage (i.e., in counts towards the operator that created the data). --------- Signed-off-by: Balaji Veeramani <balaji@anyscale.com>
