| <div class="block">Common configuration finalization for packing algorithms |
| Packing algorithms that extend this class should assume that: |
| <p> |
| 1. Instance default resources are read from: |
| heron.resources.instance.ram, |
| heron.resources.instance.cpu, |
| heron.resources.instance.disk |
| <p> |
| 2. Padding resource percentage is read from: |
| topology.container.padding.percentage |
| or taken from PackingUtils.DEFAULT_CONTAINER_PADDING_PERCENTAGE |
| <p> |
| 3. Padding resource values are read from: |
| topology.container.ram.padding or taken from PackingUtils.DEFAULT_CONTAINER_RAM_PADDING, |
| topology.container.cpu.padding or taken from PackingUtils.DEFAULT_CONTAINER_CPU_PADDING |
| <p> |
| 4. Max number of instances per container is read from: |
| topology.container.max.instances |
| or taken from PackingUtils.DEFAULT_MAX_NUM_INSTANCES_PER_CONTAINER |
| <p> |
| 5. Container resources requirements are read from: |
| topology.container.cpu or calculated from maxNumInstancesPerContainer * instanceDefaultCpu |
| topology.container.ram or calculated from maxNumInstancesPerContainer * instanceDefaultRam |
| topology.container.disk or calculated from maxNumInstancesPerContainer * instanceDefaultDisk |
| <p> |
| 6. Padding resource is finalized by: |
| Math.max(containerResource * paddingPercentage, paddingValue) |
| <p> |
| |
| Subclasses that extend this class should just need to create PackingPlanBuilder with: |
| defaultInstanceResource, |
| maxContainerResource, |
| containerPadding, |
| componentResourceMap, |
| instanceConstraints, |
| and packingConstraints set.</div> |
