cloud-fan commented on issue #26750: [SPARK-28948][SQL] Support passing all Table metadata in TableProvider URL: https://github.com/apache/spark/pull/26750#issuecomment-561516747 This is preferred over https://github.com/apache/spark/pull/26297, because 1. This follows the existing API style, so much less diff. 2. It's hard to decouple scheme and partition inference. For example, file source needs to infer partitioning before reporting its schema, as partition columns are part of the table schema.
