AWS::GameLift::GameSessionQueue

The AWS::GameLift::GameSessionQueue resource establishes a queue for processing requests to create new game sessions. A queue identifies where new game sessions can be hosted by specifying a list of destinations (fleets or aliases). It also sets how long requests can wait in the queue before timing out. You can set up a queue with destinations in multiple Regions.

Syntax

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

JSON


{
  "Type" : "AWS::GameLift::GameSessionQueue",
  "Properties" : {
      "Destinations" : [ Destination, ... ],
      "Name" : String,
      "PlayerLatencyPolicies" : [ PlayerLatencyPolicy, ... ],
      "TimeoutInSeconds" : Integer
    }
}

YAML


Type: AWS::GameLift::GameSessionQueue
Properties: 
  Destinations: 
    - Destination
  Name: String
  PlayerLatencyPolicies: 
    - PlayerLatencyPolicy
  TimeoutInSeconds: Integer

Properties

Destinations

A list of fleets that can be used to fulfill game session placement requests in the queue. Fleets are identified by either a fleet ARN or a fleet alias ARN. Destinations are listed in default preference order.

Required: No

Type: List of Destination

Update requires: No interruption

Name

A descriptive label that is associated with game session queue. Queue names must be unique within each Region.

Required: Yes

Type: String

Minimum: 1

Maximum: 256

Pattern: [a-zA-Z0-9-]+|^arn:.*:gamesessionqueue\/[a-zA-Z0-9-]+

Update requires: Replacement

PlayerLatencyPolicies

A collection of latency policies to apply when processing game sessions placement requests with player latency information. Multiple policies are evaluated in order of the maximum latency value, starting with the lowest latency values. With just one policy, the policy is enforced at the start of the game session placement for the duration period. With multiple policies, each policy is enforced consecutively for its duration period. For example, a queue might enforce a 60-second policy followed by a 120-second policy, and then no policy for the remainder of the placement. A player latency policy must set a value for MaximumIndividualPlayerLatencyMilliseconds. If none is set, this API request fails.

Required: No

Type: List of PlayerLatencyPolicy

Update requires: No interruption

TimeoutInSeconds

The maximum time, in seconds, that a new game session placement request remains in the queue. When a request exceeds this time, the game session placement changes to a TIMED_OUT status.

Required: No

Type: Integer

Minimum: 0

Update requires: No interruption

Return Values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the name of the game session queue, which is unique within each Region.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Arn: The unique Amazon Resource Name (ARN) for the GameSessionQueue.
Name: A descriptive label that is associated with a game session queue. Names are unique within each Region.

Examples

Create a Game Session Queue

The following example creates a GameLift game session queue named MyGameSessionQueue. The queue is configured with two destinations, one using a fleet ID and one using an alias ID. The queue has a latency policy.
