This is a hack because even from the DataFrameWriter the infer schema is called - even though we accept any schema.
This is a hack because even from the DataFrameWriter the infer schema is called - even though we accept any schema.
So check the stack where we are coming from and it allows to bail out early since we don't care about the schema on a write op at all.
- returns
true if we are in a write op, this is a hack.
