AWS::Deadline::Queue WeightedBalancedSchedulingConfiguration
Configuration for weighted balanced scheduling. Workers are assigned to jobs based on a weighted formula:
weight = (priority * priorityWeight) + (errors * errorWeight) +
((currentTime - submissionTime) * submissionTimeWeight) +
((renderingTasks - renderingTaskBuffer) * renderingTaskWeight)
The job with the highest calculated weight is scheduled first. Workers are distributed evenly amongst jobs with the same weight.
Syntax
To declare this entity in your CloudFormation template, use the following syntax:
JSON
{ "ErrorWeight" :Number, "MaxPriorityOverride" :SchedulingMaxPriorityOverride, "MinPriorityOverride" :SchedulingMinPriorityOverride, "PriorityWeight" :Number, "RenderingTaskBuffer" :Integer, "RenderingTaskWeight" :Number, "SubmissionTimeWeight" :Number}

Properties
ErrorWeight-
The weight applied to the number of errors on a job. A negative value means jobs without errors are scheduled first. A value of
0means errors are ignored. The default value is-10.0.Required: No
Type: Number
Minimum:
-10000Maximum:
10000Update requires: No interruption
MaxPriorityOverride-
Overrides the weighted scheduling formula for jobs at the maximum priority (100). When set, jobs with priority 100 are always scheduled first regardless of their calculated weight. When absent, maximum priority jobs use the standard weighted formula.
Required: No
Type: SchedulingMaxPriorityOverride
Update requires: No interruption
MinPriorityOverride-
Overrides the weighted scheduling formula for jobs at the minimum priority (0). When set, jobs with priority 0 are always scheduled last regardless of their calculated weight. When absent, minimum priority jobs use the standard weighted formula.
Required: No
Type: SchedulingMinPriorityOverride
Update requires: No interruption
PriorityWeight-
The weight applied to job priority in the scheduling formula. Higher values give more influence to job priority. A value of
0means priority is ignored. The default value is100.0.Required: No
Type: Number
Minimum:
0Maximum:
10000Update requires: No interruption
RenderingTaskBuffer-
The rendering task buffer is subtracted from the number of rendering tasks before applying the rendering task weight. This creates a stickiness effect where workers prefer to stay with their current job. Higher values make workers stickier. The default value is
1. The buffer is only applied in the weight calculation for a job if the worker is currently assigned to that job.Required: No
Type: Integer
Minimum:
0Maximum:
1000Update requires: No interruption
RenderingTaskWeight-
The weight applied to the number of tasks currently rendering on a job. A negative value means jobs that are not already rendering are scheduled next. A value of
0means the rendering state is ignored. The default value is-100.0.Required: No
Type: Number
Minimum:
-10000Maximum:
10000Update requires: No interruption
SubmissionTimeWeight-
The weight applied to job submission time. A positive value means earlier jobs are scheduled first. A value of
0means submission time is ignored. The default value is3.0.Required: No
Type: Number
Minimum:
0Maximum:
10000Update requires: No interruption
