Data representation is up to you and your app.
You can of course keep all your data in a massive double[] and use a
flyweight feature when iterating over the double array. This would give you
a single feature, the featureId based on and index, the geometry based on
the double[index*2,index*2+1]. No need to *store* your contents as
features, only adapt to them as needed for GeoTools to draw.
Try running through the ContentDataStore tutorial.
