describe-global-table-settings

Description

Describes Region-specific settings for a global table.

Note

This operation only applies to Version 2017.11.29 of global tables.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-global-table-settings
--global-table-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--global-table-name (string)

The name of the global table to describe.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To get information about a DynamoDB global table’s settings

The following describe-global-table-settings example displays the settings for the MusicCollection global table.

aws dynamodb describe-global-table-settings \
    --global-table-name MusicCollection

Output:

{
    "GlobalTableName": "MusicCollection",
    "ReplicaSettings": [
        {
            "RegionName": "us-east-1",
            "ReplicaStatus": "ACTIVE",
            "ReplicaProvisionedReadCapacityUnits": 10,
            "ReplicaProvisionedReadCapacityAutoScalingSettings": {

Output

GlobalTableName -> (string)

The name of the global table.

ReplicaSettings -> (list)

The Region-specific settings for the global table.

(structure)

Represents the properties of a replica.

RegionName -> (string)

The Region name of the replica.

ReplicaStatus -> (string)

The current state of the Region:

• CREATING - The Region is being created.

• UPDATING - The Region is being updated.

• DELETING - The Region is being deleted.

• ACTIVE - The Region is ready for use.

ReplicaBillingModeSummary -> (structure)

The read/write capacity mode of the replica.

BillingMode -> (string)

Controls how you are charged for read and write throughput and how you manage capacity. This setting can be changed later.

• PROVISIONED - Sets the read/write capacity mode to PROVISIONED . We recommend using PROVISIONED for predictable workloads.

• PAY_PER_REQUEST - Sets the read/write capacity mode to PAY_PER_REQUEST . We recommend using PAY_PER_REQUEST for unpredictable workloads.

LastUpdateToPayPerRequestDateTime -> (timestamp)

Represents the time when PAY_PER_REQUEST was last set as the read/write capacity mode.

ReplicaProvisionedReadCapacityUnits -> (long)

The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .

ReplicaProvisionedReadCapacityAutoScalingSettings -> (structure)

Auto scaling settings for a global table replica’s read capacity units.

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 the auto scaling policy.

ScalingPolicies -> (list)

Information about the scaling policies.

(structure)

Represents the properties of the scaling policy.

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).
