## Which issue does this PR close? Follow on to https://github.com/apache/arrow-datafusion/pull/7793 ## Rationale for this change While integrating https://github.com/apache/arrow-datafusion/pull/7793 into IOx, I found I had to change all our ExecutionPlan implementations with the boilerplate (but non trivial) `ExecutionPlan::statistics` implementation ```rust fn statistics(&self) -> Result<datafusion::physical_plan::Statistics, DataFusionError> { Ok(datafusion::physical_plan::Statistics::new_unknown(&self.schema())) } ``` In order the ease the upgrade pain for others, we should provide this as a default. ## What changes are included in this PR? 1. Provide a default impl for `ExecutionPlan::statistics` 2. Improve documentation ## Are these changes tested? Covered by existing tests ## Are there any user-facing changes? Hopefully a slightly less painful upgrade for https://github.com/apache/arrow-datafusion/pull/7793 -- This is an automated message from the Apache Git Service.
