DataFusion currently has 2 sets of statics functions which some people (myself included) find confusing. I propose to mark the copy that is not used as deprecated in preparation for removal in a future release.
Major APIs to deprecate are: The Distribution in datafusion/expr-common/src/statistics.rs PhysicalExpr::evaluate_statistics PhysicalExpr::propagate_statistics Please join the conversation here if you are interested https://github.com/apache/datafusion/pull/22071 Andrew
