Hello,

I am setting up a standalone flink cluster and I am wondering what’s the best 
way to distribute TaskManagers.  Do we usually launch one TaskManager (with 
many slots) per node or multiple TaskManagers per node (with smaller number of 
slots per tm) ?  Also with one TaskManager per node, I am seeing that TM 
launches with only 30GB JVM heap by default while the node has 180 GB. Why is 
it not launching with more memory since there is a lot available? 

Thank you very much!
