Hi,

For SaveMode.Append, the doc
https://spark.apache.org/docs/latest/sql-data-sources-load-save-functions.html#save-modes
says

*When saving a DataFrame to a data source, if data/table already exists,
contents of the DataFrame are expected to be appended to existing data*

However it does not specify behavior when the table does not exist.
Does that throw exception or create the table or a NO-OP?

Thanks,
Shubham
