This will include conditional support for sizeBasedWeight > style adjustment > Optionally, based on a conditional configuration to enable sizeBasedWeight > (default false), an adjustment to boost larger applications (to offset the > natural preference for smaller applications) will adjust the resource usage > value based on demand, dividing it by the below value: > Math.log1p(app memory demand) / Math.log(2); > In cases where the above is indeterminate (two applications are equal after > this comparison), behavior falls back to comparison based on the application > id, which is generally lexically FIFO for that comparison -- This message was sent by Atlassian JIRA (v6.3.4#6332)
