## Which issue does this PR close? Part of #7013 Related to #7869 and https://github.com/apache/arrow-datafusion/issues/9171 ## Rationale for this change 1. We rely heavily on PruningPredicate in InfluxDB to prune data based on catalog information, so I want an easier way to point our engineers at it and understand how it works. 2. We also had some non trivial confusion internally about how/if pruning predicates handled unknown column values, which I wanted to document ## What changes are included in this PR? 1. Add `pruning.rs` example to datafusion-examples with an annotated guide to using `PruningPredicate 2. Add link to the example in the `PruningPredicate` API docs ## Are these changes tested? Yes, as part of CI ## Are there any user-facing changes? A new example, no code changes -- This is an automated message from the Apache Git Service.
