Problem $3$: Define Output Sinks

We will now define in$-$memory output sinks for both of the transformed DataFrames we created in Problem $2.$

We will do this by creating a DataStreamWriter object for each of these DataFrames.

Create a DataStreamWriter object for the type$\_$summary streaming DataFrame and another one for the

destinations streaming DataFrame. Both DataStreamWriter objects should write to in$-$memory tables

in complete mode. Name the resulting tables type$\_$summary and destinations
