AWS::Cassandra::Table AutoScalingSetting

The optional auto scaling settings for a table with provisioned throughput capacity.

To turn on auto scaling for a table in throughputMode:PROVISIONED, you must specify the following parameters.

Configure the minimum and maximum capacity units. The auto scaling policy ensures that capacity never goes below the minimum or above the maximum range.

• minimumUnits: The minimum level of throughput the table should always be ready to support. The value must be between 1 and the max throughput per second quota for your account (40,000 by default).

• maximumUnits: The maximum level of throughput the table should always be ready to support. The value must be between 1 and the max throughput per second quota for your account (40,000 by default).

• scalingPolicy: Amazon Keyspaces supports the target tracking scaling policy. The auto scaling target is a percentage of the provisioned capacity of the table.

For more information, see Managing throughput capacity automatically with Amazon Keyspaces auto scaling in the Amazon Keyspaces Developer Guide.

Syntax

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

JSON

{
  "AutoScalingDisabled" : Boolean,
  "MaximumUnits" : Integer,
  "MinimumUnits" : Integer,
  "ScalingPolicy" : ScalingPolicy
}

YAML

  AutoScalingDisabled: Boolean
  MaximumUnits: Integer
  MinimumUnits: Integer
  ScalingPolicy: 
    ScalingPolicy

Properties

AutoScalingDisabled

This optional parameter enables auto scaling for the table if set to false.

Required: No

Type: Boolean

Update requires: No interruption

MaximumUnits

Manage costs by specifying the maximum amount of throughput to provision. The value must be between 1 and the max throughput per second quota for your account (40,000 by default).

Required: No

Type: Integer

Minimum: 1

Update requires: No interruption

MinimumUnits

The minimum level of throughput the table should always be ready to support. The value must be between 1 and the max throughput per second quota for your account (40,000 by default).

Required: No

Type: Integer

Minimum: 1

Update requires: No interruption

ScalingPolicy

Amazon Keyspaces supports the target tracking auto scaling policy. With this policy, Amazon Keyspaces auto scaling ensures that the table's ratio of consumed to provisioned capacity stays at or near the target value that you specify. You define the target value as a percentage between 20 and 90.

Required: No

Type: ScalingPolicy

Update requires: No interruption
