UpdateTable - Amazon DynamoDB

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.
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's executing, the table status changes from ACTIVE to UPDATING. While it's UPDATING, you can't issue another UpdateTable request. When the table returns to the ACTIVE state, the UpdateTable operation is complete.

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. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

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.

PAY_PER_REQUEST - We recommend using PAY_PER_REQUEST for most DynamoDB workloads. PAY_PER_REQUEST sets the billing mode to On-demand capacity mode.
PROVISIONED - We recommend using PROVISIONED for steady workloads with predictable growth where capacity requirements can be reliably forecasted. PROVISIONED sets the billing mode to Provisioned capacity mode.

Type: String

Valid Values: PROVISIONED | PAY_PER_REQUEST

Required: No

DeletionProtectionEnabled

Indicates whether deletion protection is to be enabled (true) or disabled (false) on the table.

Type: Boolean

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

GlobalTableWitnessUpdates

A list of witness updates for a MRSC global table. A witness provides a cost-effective alternative to a full replica in a MRSC global table by maintaining replicated change data written to global table replicas. You cannot perform read or write operations on a witness. For each witness, you can request one action:

Create - add a new witness to the global table.
Delete - remove a witness from the global table.

You can create or delete only one witness per UpdateTable operation.

For more information, see Multi-Region strong consistency (MRSC) in the Amazon DynamoDB Developer Guide

Type: Array of GlobalTableWitnessGroupUpdate objects

Array Members: Fixed number of 1 item.

Required: No

MultiRegionConsistency

Specifies the consistency mode for a new global table. This parameter is only valid when you create a global table by specifying one or more Create actions in the ReplicaUpdates action list.

You can specify one of the following consistency modes:

EVENTUAL: Configures a new global table for multi-Region eventual consistency (MREC). This is the default consistency mode for global tables.
STRONG: Configures a new global table for multi-Region strong consistency (MRSC).

If you don't specify this field, the global table consistency mode defaults to EVENTUAL. For more information about global tables consistency modes, see Consistency modes in DynamoDB developer guide.

Type: String

Valid Values: EVENTUAL | STRONG

Required: No

OnDemandThroughput

Updates the maximum number of read and write units for the specified table in on-demand capacity mode. If you use this parameter, you must specify MaxReadRequestUnits, MaxWriteRequestUnits, or both.

Type: OnDemandThroughput object

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.

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 ValidationException 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

TableClass

The table class of the table to be updated. Valid values are STANDARD and STANDARD_INFREQUENT_ACCESS.

Type: String

Valid Values: STANDARD | STANDARD_INFREQUENT_ACCESS

Required: No

WarmThroughput

Represents the warm throughput (in read units per second and write units per second) for updating a table.

Type: WarmThroughput 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.

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.

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.

GetRecords was called with a value of more than 1000 for the limit request parameter.

More than 2 processes are reading from the same streams shard at the same time. Exceeding this limit may result in request throttling.

HTTP Status Code: 400

ResourceInUseException

The operation conflicts with the resource's availability. For example:

You attempted to recreate an existing table.
You tried to delete a table currently in the CREATING state.
You tried to update a resource that was already being updated.

When appropriate, wait for the ongoing update to complete and attempt the request again.

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

Examples Modify Provisioned Write Throughput

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