Subject Re: Flink Minimal requirements

Hi Kristof,

Flink doesn't have any specific requirements.
You can run Flink on a single node with just one core. The number of
threads is dynamic.

However, you'll probably want to configure memory usage if the default
values are greater than what the actual machine has.
