Amazon DynamoDB
API Reference

UpdateTable

Modifies the provisioned throughput settings, global secondary indexes, or DynamoDB Streams settings for a given table.

You can only perform one of the following operations at once:

  • Modify the provisioned throughput settings of the table.

  • Enable or disable DynamoDB Streams on the table.

  • Remove a global secondary index from the table.

  • Create a new global secondary index on the table. After the index begins backfilling, you can use UpdateTable to perform other operations.

UpdateTable is an asynchronous operation; while it is executing, the table status changes from ACTIVE to UPDATING. While it is UPDATING, you cannot issue another UpdateTable request. When the table returns to the ACTIVE state, the UpdateTable operation is complete.

Request Syntax

{ "AttributeDefinitions": [ { "AttributeName": "string", "AttributeType": "string" } ], "BillingMode": "string", "GlobalSecondaryIndexUpdates": [ { "Create": { "IndexName": "string", "KeySchema": [ { "AttributeName": "string", "KeyType": "string" } ], "Projection": { "NonKeyAttributes": [ "string" ], "ProjectionType": "string" }, "ProvisionedThroughput": { "ReadCapacityUnits": number, "WriteCapacityUnits": number } }, "Delete": { "IndexName": "string" }, "Update": { "IndexName": "string", "ProvisionedThroughput": { "ReadCapacityUnits": number, "WriteCapacityUnits": number } } } ], "ProvisionedThroughput": { "ReadCapacityUnits": number, "WriteCapacityUnits": number }, "ReplicaUpdates": [ { "Create": { "GlobalSecondaryIndexes": [ { "IndexName": "string", "ProvisionedThroughputOverride": { "ReadCapacityUnits": number } } ], "KMSMasterKeyId": "string", "ProvisionedThroughputOverride": { "ReadCapacityUnits": number }, "RegionName": "string" }, "Delete": { "RegionName": "string" }, "Update": { "GlobalSecondaryIndexes": [ { "IndexName": "string", "ProvisionedThroughputOverride": { "ReadCapacityUnits": number } } ], "KMSMasterKeyId": "string", "ProvisionedThroughputOverride": { "ReadCapacityUnits": number }, "RegionName": "string" } } ], "SSESpecification": { "Enabled": boolean, "KMSMasterKeyId": "string", "SSEType": "string" }, "StreamSpecification": { "StreamEnabled": boolean, "StreamViewType": "string" }, "TableName": "string" }

Request Parameters

The request accepts the following data in JSON format.

Note

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

TableName

The name of the table to be updated.

Type: String

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

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

Required: Yes

AttributeDefinitions

An array of attributes that describe the key schema for the table and indexes. If you are adding a new global secondary index to the table, AttributeDefinitions must include the key element(s) of the new index.

Type: Array of AttributeDefinition objects

Required: No

BillingMode

Controls how you are charged for read and write throughput and how you manage capacity. When switching from pay-per-request to provisioned capacity, initial provisioned capacity values must be set. The initial provisioned capacity values are estimated based on the consumed read and write capacity of your table and global secondary indexes over the past 30 minutes.

  • PROVISIONED - We recommend using PROVISIONED for predictable workloads. PROVISIONED sets the billing mode to Provisioned Mode.

  • PAY_PER_REQUEST - We recommend using PAY_PER_REQUEST for unpredictable workloads. PAY_PER_REQUEST sets the billing mode to On-Demand Mode.

Type: String

Valid Values: PROVISIONED | PAY_PER_REQUEST

Required: No

GlobalSecondaryIndexUpdates

An array of one or more global secondary indexes for the table. For each index in the array, you can request one action:

  • Create - add a new global secondary index to the table.

  • Update - modify the provisioned throughput settings of an existing global secondary index.

  • Delete - remove a global secondary index from the table.

You can create or delete only one global secondary index per UpdateTable operation.

For more information, see Managing Global Secondary Indexes in the Amazon DynamoDB Developer Guide.

Type: Array of GlobalSecondaryIndexUpdate objects

Required: No

ProvisionedThroughput

The new provisioned throughput settings for the specified table or index.

Type: ProvisionedThroughput object

Required: No

ReplicaUpdates

A list of replica update actions (create, delete, or update) for the table.

Note

This property only applies to Version 2019.11.21 of global tables.

Type: Array of ReplicationGroupUpdate objects

Array Members: Minimum number of 1 item.

Required: No

SSESpecification

The new server-side encryption settings for the specified table.

Type: SSESpecification object

Required: No

StreamSpecification

Represents the DynamoDB Streams configuration for the table.

Note

You receive a ResourceInUseException if you try to enable a stream on a table that already has a stream, or if you try to disable a stream on a table that doesn't have a stream.

Type: StreamSpecification object

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.

TableDescription

Represents the properties of the table.

Type: TableDescription object

Errors

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

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.

Up to 50 simultaneous table operations are allowed per account. These operations include CreateTable, UpdateTable, DeleteTable,UpdateTimeToLive, RestoreTableFromBackup, and RestoreTableToPointInTime.

The only exception is when you are creating a table with one or more secondary indexes. You can have up to 25 such requests running at a time; however, if the table or index specifications are complex, DynamoDB might temporarily reduce the number of concurrent operations.

There is a soft account limit of 256 tables.

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

ResourceNotFoundException

The operation tried to access a nonexistent table or index. The resource might not be specified correctly, or its status might not be ACTIVE.

HTTP Status Code: 400

Example

Modify Provisioned Write Throughput

This example changes both the provisioned read and write throughput of the Thread table to 10 capacity units.
