niebayes opened a new issue, #15474: URL: https://github.com/apache/datafusion/issues/15474
The `UnionExec` operator has two helper functions for merging statistics from multiple input operators. Such a functionality is also needed by my project. Can we provide a public helper function for merging multiple statistics into a single statistics? This helper function is based on the current `stats_union` and `col_stats_union` functions, and will validate the schema. -- This is an automated message from the Apache Git Service.
