Hi all,

The Flink docs recommend "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" [1].

Would it be worthwhile to recommend a higher memory reserve and note that
the file write and read-ahead caches must also fit in memory?
