DataFu 1.0
As we can see, the DataFu version provides a noticable improvement in both metrics. Glad to know that work wasn't all for naught. Creating a custom purpose UDF Many UDFs, such as those presented in the previous section, are general purpose. DataFu serves to collect these UDFs and make sure they are tested and easily available. If you are writing such a UDF, then we will happily accept contribution
