Description

Currently I have a committer that has read a Parquet file that it is then trying to add to a Delta Lake table. However the current create_add function really only applies to writers of the Parquet file, as it uses the format::FileMetaData and readers have the file:metadata::FileMetaData.

On our fork we have a function that allows a reader to create an Add: 1a2dd95

Use Case

Allows backfilling of Parquet files into Delta Lake tables.
