-----------------------------------

             Summary: [Rust][DataFusion] Make the custom source implementation API more explicit
                 Key: ARROW-10389
                 URL: https://issues.apache.org/jira/browse/ARROW-10389
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust, Rust - DataFusion
            Reporter: Remi Dettai


As you can see in [ARROW-10368|https://issues.apache.org/jira/browse/ARROW-10368], I had quite a hard time figuring out that the TableProvider trait could be used to provide custom source implementations for DataFusion.

I think that adding a {{read_table(provider: Box<dyn TableProvider + Send + Sync>) -> Result<Arc<dyn DataFrame>>}} method to the ExecutionContext and an example in the tests and/or in the examples folder would make the API more explicit.
