No, that won't work. The SQL nodes need a fast connection to the data nodes as well.

The figure shown for maximum heartbeat (HeartbeatIntervalDbApi) is just what the code allows due to the data type of the parameter--the practical maximum is at most a few seconds. I certainly wouldn't try to set it for some time measured in days, or even hours. :)
