Can anyone tell me briefly what kind of ETL jobs that spotfire data wrangling can't do?

I know that spotfire allows us to do a bit of data modelling using data wrangling. But, I just wanted to know its limitations as we know that they are many ETL tools to perform the data cleaning and preparation part. So, can anyone let me know briefly certain things that can be done in ETL tools but cannot be done in spotfire? As spotfire is basically build for visualizations. Thanks.
