Adjustable share to workload affects how resources are allocated and reclaimed from consumers.
Use this feature if you want share ratio to always be honored when two or more consumers are competing for resources. Whenever consumers compete for resources, resources are reclaimed and distributed in proportion to share ratio. Workload among all consumers is taken into account and resource distribution is adjusted according to workload. Consumers can reclaim more resources than their configured planned share ratio.
When this feature is not enabled (default behavior), resources are distributed according to configured share ratio but resource distribution is not adjusted according to workload. When two consumers compete for resources, consumers that have not received up to their share ratio can only reclaim resources up to their share ratio. When consumers have reached their share ratio, distribution of additional resources to consumers is done in First-Come, First-Served order.
