ScalingConfiguration¶
Structure Class¶
dataclass
¶
Bases: _SerdeShape
Contains the scaling configuration of an Aurora Serverless v1 DB cluster.
For more information, see Using Amazon Aurora Serverless v1 in the Amazon Aurora User Guide.
Attributes¶

instance-attribute
¶
auto_pause: bool | None = ...
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).
Note
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.

instance-attribute
¶
max_capacity: int | None = ...
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.

instance-attribute
¶
min_capacity: int | None = ...
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.

¶
seconds_before_timeout: int | None = ...
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.
class-attribute
instance-attribute
¶
seconds_until_auto_pause: int | None = ...
The time, in seconds, before an Aurora DB cluster in serverless mode
is paused.
Specify a value between 300 and 86,400 seconds.
class-attribute
instance-attribute
¶
timeout_action: str | None = ...
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.
Warning
If you specify ForceApplyCapacityChange, connections that prevent
Aurora Serverless v1 from finding a scaling point might be dropped.
For more information, see Autoscaling for Aurora Serverless v1 in the Amazon Aurora User Guide.
