We should also include a section in the README talking about this sample and referring to it with a link - this way it will be easier for our customers to find it rather than expecting them to just look at our samples without guidance.
This README bit should also have some comparisons/ percentage differences listed so that users can see how beneficial it might be for them to use it, as well as having the notice on how this will explode their RU consumption and how they should be aware of this if they choose to use it.
