UpdateGlobalTableSettings

Updates settings for a global table.

Important

This operation only applies to Version 2017.11.29 (Legacy) of global tables. We recommend using Version 2019.11.21 (Current) when creating new global tables, as it provides greater flexibility, higher efficiency and consumes less write capacity than 2017.11.29 (Legacy). To determine which version you are using, see Determining the version. To update existing global tables from version 2017.11.29 (Legacy) to version 2019.11.21 (Current), see Updating global tables.

Request Parameters

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

GlobalTableName

The name of the global table

Required: No

GlobalTableGlobalSecondaryIndexSettingsUpdate

Represents the settings of a global secondary index for a global table that will be modified.

Auto scaling settings for managing provisioned write capacity for the global table.

Type: AutoScalingSettingsUpdate object

Required: No

GlobalTableProvisionedWriteCapacityUnits

Type: Long

Valid Range: Minimum value of 1.

Required: No

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

GlobalTableName

The name of the global table.

Type: String

Length Constraints: Minimum length of 3. Maximum length of 255.

Pattern: [a-zA-Z0-9_.-]+

ReplicaSettings

The Region-specific settings for the global table.

Type: Array of ReplicaSettingsDescription objects

Errors

For information about the errors that are common to all actions, see Common Errors.

GlobalTableNotFoundException

The specified global table does not exist.

HTTP Status Code: 400

IndexNotFoundException

The operation tried to access a nonexistent index.

HTTP Status Code: 400

InternalServerError

An error occurred on the server side.

HTTP Status Code: 500

LimitExceededException

There is no limit to the number of daily on-demand backups that can be taken.

For most purposes, up to 500 simultaneous table operations are allowed per account. These operations include CreateTable, UpdateTable, DeleteTable,UpdateTimeToLive, RestoreTableFromBackup, and RestoreTableToPointInTime.

When you are creating a table with one or more secondary indexes, you can have up to 250 such requests running at a time. However, if the table or index specifications are complex, then DynamoDB might temporarily reduce the number of concurrent operations.

When importing into DynamoDB, up to 50 simultaneous import table operations are allowed per account.

There is a soft account quota of 2,500 tables.

HTTP Status Code: 400

ReplicaNotFoundException

The specified replica is no longer part of the global table.

HTTP Status Code: 400

ResourceInUseException

The operation conflicts with the resource's availability. For example, you attempted to recreate an existing table, or tried to delete a table currently in the CREATING state.

HTTP Status Code: 400
