# AWS::Batch::SchedulingPolicy ShareAttributes
<a name="aws-properties-batch-schedulingpolicy-shareattributes"></a>

Specifies the weights for the share identifiers for the fair-share policy. Share identifiers that aren't included have a default weight of `1.0`.

## Syntax
<a name="aws-properties-batch-schedulingpolicy-shareattributes-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-batch-schedulingpolicy-shareattributes-syntax.json"></a>

```
{
  "[ShareIdentifier](#cfn-batch-schedulingpolicy-shareattributes-shareidentifier)" : String,
  "[WeightFactor](#cfn-batch-schedulingpolicy-shareattributes-weightfactor)" : Number
}
```

### YAML
<a name="aws-properties-batch-schedulingpolicy-shareattributes-syntax.yaml"></a>

```
  [ShareIdentifier](#cfn-batch-schedulingpolicy-shareattributes-shareidentifier): String
  [WeightFactor](#cfn-batch-schedulingpolicy-shareattributes-weightfactor): Number
```

## Properties
<a name="aws-properties-batch-schedulingpolicy-shareattributes-properties"></a>

`ShareIdentifier`  <a name="cfn-batch-schedulingpolicy-shareattributes-shareidentifier"></a>
A share identifier or share identifier prefix. If the string ends with an asterisk (\$1), this entry specifies the weight factor to use for share identifiers that start with that prefix. The list of share identifiers in a fair-share policy can't overlap. For example, you can't have one that specifies a `shareIdentifier` of `UserA*` and another that specifies a `shareIdentifier` of `UserA1`.  
There can be no more than 500 share identifiers active in a job queue.  
The string is limited to 255 alphanumeric characters, and can be followed by an asterisk (\$1).  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`WeightFactor`  <a name="cfn-batch-schedulingpolicy-shareattributes-weightfactor"></a>
The weight factor for the share identifier. The default value is 1.0. A lower value has a higher priority for compute resources. For example, jobs that use a share identifier with a weight factor of 0.125 (1/8) get 8 times the compute resources of jobs that use a share identifier with a weight factor of 1.  
The smallest supported value is 0.0001, and the largest supported value is 999.9999.  
*Required*: No  
*Type*: Number  
*Minimum*: `0`  
*Maximum*: `1000`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
