Review Comment: Here is a suggestion from https://docs.rs/datafusion/latest/datafusion/physical_optimizer/pruning/struct.PruningPredicate.html ```suggestion This crate is a submodule of DataFusion that contains pruning logic, to analyze filter expressions with statistics such as min/max values and null counts, proving files / large subsections of files can be skipped without reading the actual data. ``` We could also add a link to the pruning predicate docs at https://docs.rs/datafusion/latest/datafusion/physical_optimizer/pruning/struct.PruningPredicate.html too -- This is an automated message from the Apache Git Service.
