Set the capacity of an Aurora Serverless v1 DB cluster to a specific value.
Aurora Serverless v1 scales seamlessly based on the workload on the DB cluster. In
some cases, the capacity might not scale fast enough to meet a sudden change in workload,
such as a large number of new transactions. Call ModifyCurrentDBClusterCapacity
to set the capacity explicitly.
After this call sets the DB cluster capacity, Aurora Serverless v1 can automatically scale the DB cluster based on the cooldown period for scaling up and the cooldown period for scaling down.
For more information about Aurora Serverless v1, see Using Amazon Aurora Serverless v1 in the Amazon Aurora User Guide.
If you call ModifyCurrentDBClusterCapacity
with the default TimeoutAction
,
connections that prevent Aurora Serverless v1 from finding a scaling point might be
dropped. For more information about scaling points, see
Autoscaling for Aurora Serverless v1 in the Amazon Aurora User Guide.
This operation only applies to Aurora Serverless v1 DB clusters.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginModifyCurrentDBClusterCapacity and EndModifyCurrentDBClusterCapacity.
