# ScalingConfiguration
<a name="API_ScalingConfiguration"></a>

Contains the scaling configuration of an Aurora Serverless v1 DB cluster.

For more information, see [Using Amazon Aurora Serverless v1](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless.html) in the *Amazon Aurora User Guide*.

**Note**  
In the following list, the required parameters are described first.

 ** AutoPause **   
Indicates whether to allow or disallow automatic pause for an Aurora DB cluster in `serverless` DB engine mode. A DB cluster can be paused only when it's idle (it has no connections).  
If a DB cluster is paused for more than seven days, the DB cluster might be backed up with a snapshot. In this case, the DB cluster is restored when there is a request to connect to it.
Type: Boolean  
Required: No

 ** MaxCapacity **   
The maximum capacity for an Aurora DB cluster in `serverless` DB engine mode.  
For Aurora MySQL, valid capacity values are `1`, `2`, `4`, `8`, `16`, `32`, `64`, `128`, and `256`.  
For Aurora PostgreSQL, valid capacity values are `2`, `4`, `8`, `16`, `32`, `64`, `192`, and `384`.  
The maximum capacity must be greater than or equal to the minimum capacity.  
Type: Integer  
Required: No

 ** MinCapacity **   
The minimum capacity for an Aurora DB cluster in `serverless` DB engine mode.  
For Aurora MySQL, valid capacity values are `1`, `2`, `4`, `8`, `16`, `32`, `64`, `128`, and `256`.  
For Aurora PostgreSQL, valid capacity values are `2`, `4`, `8`, `16`, `32`, `64`, `192`, and `384`.  
The minimum capacity must be less than or equal to the maximum capacity.  
Type: Integer  
Required: No

 ** SecondsBeforeTimeout **   
The amount of time, in seconds, that Aurora Serverless v1 tries to find a scaling point to perform seamless scaling before enforcing the timeout action. The default is 300.  
Specify a value between 60 and 600 seconds.  
Type: Integer  
Required: No

 ** SecondsUntilAutoPause **   
The time, in seconds, before an Aurora DB cluster in `serverless` mode is paused.  
Specify a value between 300 and 86,400 seconds.  
Type: Integer  
Required: No

 ** TimeoutAction **   
The action to take when the timeout is reached, either `ForceApplyCapacityChange` or `RollbackCapacityChange`.  
 `ForceApplyCapacityChange` sets the capacity to the specified value as soon as possible.  
 `RollbackCapacityChange`, the default, ignores the capacity change if a scaling point isn't found in the timeout period.  
If you specify `ForceApplyCapacityChange`, connections that prevent Aurora Serverless v1 from finding a scaling point might be dropped.

Type: String  
Required: No
