[GitHub] [arrow-datafusion] Ted-Jiang opened a new issue, #2768: Support multiple paths for ListingTableScanNode

Ted-Jiang opened a new issue, #2768:
URL: https://github.com/apache/arrow-datafusion/issues/2768

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   Now `ListingTableConfig`
   ```
   pub struct ListingTableConfig {
       /// Path on the `ObjectStore` for creating `ListingTable`.
       pub table_path: ListingTableUrl,
       /// Optional `SchemaRef` for the to be created `ListingTable`.
       pub file_schema: Option<SchemaRef>,
       /// Optional `ListingOptions` for the to be created `ListingTable`.
       pub options: Option<ListingOptions>,
   }
   
   ```
   
   Sometimes we need pass multi path in `ListingTableConfig` like after partition prune we only need scan 
   `/table/2020/01` and `/table/2020/03` without  `/table/2020/02`
   So we need pass 
   
   ```
   pub struct ListingTableConfig {
       /// Path on the `ObjectStore` for creating `ListingTable`.
       pub table_path: Vec<ListingTableUrl>,
       /// Optional `SchemaRef` for the to be created `ListingTable`.
       pub file_schema: Option<SchemaRef>,
       /// Optional `ListingOptions` for the to be created `ListingTable`.
       pub options: Option<ListingOptions>,
   }
   
   ```
