Re: Isolate Tasks - Run Distinct Tasks in Different Task Managers

Internally, Flink defines through SlotSharingGroup which tasks may share a task manager slot. By configuring each TaskManager to have a single slot and configuring the slot sharing groups accordingly, you can get the desired behaviour. You can specify the slot sharing group for an operator like ma
