python upload big file example

Hi Barry, there wasn't really any particular reason for 4 MB in my sample. A larger size could certainly improve overall performance (by reducing the overhead of making more connections), but it comes at the cost of making each call more likely to fail. Further, the app would have to re-upload more data for any particular failed call.

So, it's really just a tradeoff for you to make based on the use cases for your app. E.g., if you know your app is likely to be used with weak, slow, or unreliable network connections, a smaller chunk size is better. Otherwise, a larger chunk size would be good.
