########## datafusion/physical-plan/benches/compute_statistics.rs: ########## Review Comment: Covered in bf43bc7: I have added a `FilterExec` chain at depths 10/20/50. It shows ~2x cost of per-partition vs overall, and ~25x speedup over non-shared-cache baseline at depth 50. The 2x cost is expected due to the second walk, and as you were anticipating, the cache still makes it cheap enough. -- This is an automated message from the Apache Git Service.
