Description:
Currently, only the native V1 file-based streaming source can read the
`_metadata` column:
[https://github.com/apache/spark/blob/370870b7a0303e4a2c4b3dea1b479b4fcbc93f8d/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/StreamingRelation.scala#L63]
Our goal is to create an interface that allows other streaming sources to add
`{{{}_metadata`{}}} columns. For instance, we would like the Delta Streaming
source, which you can find here:
[https://github.com/delta-io/delta/blob/master/spark/src/main/scala/org/apache/spark/sql/delta/sources/DeltaDataSource.scala#L49],
to extend this interface and provide the `{{{}_metadata`{}}} column for its
underlying storage format, such as Parquet.
