Andy Grove updated ARROW-11195: ------------------------------- Summary: [Rust] [DataFusion] Built-in table providers should expose relevant fields (was: [Rust] [DataFusiion] Built-in table providers should expose relevant fields) > [Rust] [DataFusion] 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 > Priority: Major > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
