About task manager heap size Flink doc says:

... If the cluster is exclusively running Flink, the total amount of
available memory per machine minus some memory for the operating system
(maybe 1-2 GB) is a good value....

But my nodes have 2GB of ram each. There isn't an empirical count to set ram
memory or a way to estimate the ram used by the OS?
