> 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.
