jackkleeman opened a new pull request, #17476: URL: https://github.com/apache/datafusion/pull/17476
The goal of this PR is to allow cardinality statistics being passed through joins even if fields don't have max and min values set, as long as a distinct value estimate is provided. Currently we require max and min to be set, as they might be used to estimate the distinct count. This is unnecessarily conservative if distinct_count has actually been provided, in which case max and min won't be used at all and the presence of max or min has no influence over how good of an estimate it is. -- This is an automated message from the Apache Git Service.
