--global-table-name
(string)
The name of the global table
--global-table-billing-mode
(string)
The billing mode of the global table. If
GlobalTableBillingMode
is not specified, the global table defaults toPROVISIONED
capacity billing mode.
PROVISIONED
- We recommend usingPROVISIONED
for predictable workloads.PROVISIONED
sets the billing mode to Provisioned Mode .
PAY_PER_REQUEST
- We recommend usingPAY_PER_REQUEST
for unpredictable workloads.PAY_PER_REQUEST
sets the billing mode to On-Demand Mode .Possible values:
PROVISIONED
PAY_PER_REQUEST
--global-table-provisioned-write-capacity-units
(long)
The maximum number of writes consumed per second before DynamoDB returns a
ThrottlingException.
--global-table-provisioned-write-capacity-auto-scaling-settings-update
(structure)
Auto scaling settings for managing provisioned write capacity for the global table.
MinimumUnits -> (long)
The minimum capacity units that a global table or global secondary index should be scaled down to.
MaximumUnits -> (long)
The maximum capacity units that a global table or global secondary index should be scaled up to.
AutoScalingDisabled -> (boolean)
Disabled auto scaling for this global table or global secondary index.
AutoScalingRoleArn -> (string)
Role ARN used for configuring auto scaling policy.
ScalingPolicyUpdate -> (structure)
The scaling policy to apply for scaling target global table or global secondary index capacity units.
PolicyName -> (string)
The name of the scaling policy.
TargetTrackingScalingPolicyConfiguration -> (structure)
Represents a target tracking scaling policy configuration.
DisableScaleIn -> (boolean)
Indicates whether scale in by the target tracking policy is disabled. If the value is true, scale in is disabled and the target tracking policy won’t remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource. The default value is false.
ScaleInCooldown -> (integer)
The amount of time, in seconds, after a scale in activity completes before another scale in activity can start. The cooldown period is used to block subsequent scale in requests until it has expired. You should scale in conservatively to protect your application’s availability. However, if another alarm triggers a scale out policy during the cooldown period after a scale-in, application auto scaling scales out your scalable target immediately.
ScaleOutCooldown -> (integer)
The amount of time, in seconds, after a scale out activity completes before another scale out activity can start. While the cooldown period is in effect, the capacity that has been added by the previous scale out event that initiated the cooldown is calculated as part of the desired capacity for the next scale out. You should continuously (but not excessively) scale out.
TargetValue -> (double)
The target value for the metric. The range is 8.515920e-109 to 1.174271e+108 (Base 10) or 2e-360 to 2e360 (Base 2).

--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.

To update provisioned write capacity settings on a DynamoDB global table
The following update-global-table-settings
example sets the provisioned write capacity of the MusicCollection
global table to 15.
