Also, @alamb, @kosiew and @Omega359, just to be upfront with the intentions of this cli. The idea would be to follow up immediately by opening a bunch of easily reproducible Github issues with improvement opportunities in the stats propagation logic and link them to https://github.com/apache/datafusion/issues/8227. I'm expecting to create a bunch of issues that follow the same template: - Title: Improve stats estimation accuracy in X operator - Description: - The operator that is reporting high q-error on planing stats vs runtime metrics, and by how much it misses on estimations - The `dfbench statistics ...` command that reproduces the issue - The success criteria that qualifies an improvement in stats estimation there (e.g., lower q-error + no regressions in other operators) -- This is an automated message from the Apache Git Service.
