Hi! I have a question about utilization-based resource placement (specifically: placement-strategy=balanced): Assume you have two resource capacities (say A and B) on each node, and each resource also has a utilization parameter for both. Both nodes have enough capacity for a resource to be started. Consider these cases for resource R: 1) R needs A = B 2) R needs A > B 3) R needs A < B
Maybe consider these cases for each node: a) A = B b) A > B c) A < B Where would the resources be placed? (Obviously A and B are independent, so you can't say "How many A is worth one B" (or vice versa) Then, given some placement, assume that node capacity for A or B increases on a node. How large has the stickiness parameter for the resource have to be to prevent resource migration? Are there any tools to help understanding? Note: For placement-strategy=utilization it's easier: As long as there is sufficient capacity, distribute the resources on the node that has least number of resources.
