> Support data source name mapping configuration
> ----------------------------------------------
>                 Key: SPARK-25143
>                 URL:
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 2.4.0
>            Reporter: Dongjoon Hyun
>            Priority: Major
> Currently, for better UX, Apache Spark provides data source backward compatibility by
using the pre-defined built-in `backwardCompatibilityMap`.
>  * []
> Although this mapping table is maintained carefully, but it's not flexible when we have
multiple implementations like Avro/CSV/ORC.
> This issue aims to extend Spark backward-compatibility-mapping capability by allowing
users provide a custom mapping in a general manner as configuration. If a user faces some
issue with the provided mapping, he/she can override it by configuration.
