----------------------------------
Summary: [Rust] [DataFusiion] Built-in table providers should
expose relevant fields
Key: ARROW-11195
URL: https://issues.apache.org/jira/browse/ARROW-11195
Project: Apache Arrow
Issue Type: Improvement
Components: Rust - DataFusion
Reporter: Andy Grove
Assignee: Andy Grove
Fix For: 3.0.0
For projects that depend on the DataFusion logical plan, there is a breaking
change currently compared to 2.0.0 where it is not possible to introspect the
TableScan node for CSV and Parquet files to get the file path and other
meta-data (such as delimiter for CSV).
I propose adding public methods to the specific providers so that other crates
can downcast to specific implementations in order to access this data.
My specific use case is the ability to serialize a DataFusion logical plan.
