Synopsis

Invokes the UpdateTable operation against Amazon DynamoDB.

Syntax

Update-DDBTable
-TableName <String>
-AttributeDefinition <AttributeDefinition[]>
-GlobalSecondaryIndexUpdate <GlobalSecondaryIndexUpdate[]>
-ReadCapacity <Int64>
-StreamSpecification_StreamEnabled <Boolean>
-StreamSpecification_StreamViewType <StreamViewType>
-WriteCapacity <Int64>
-Force <SwitchParameter>

Description

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 Streams on the table.
  • Remove a global secondary index from the table.
  • Create a new global secondary index on the table. Once 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.

Parameters

-AttributeDefinition <AttributeDefinition[]>
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.
Required?False
Position?Named
Accept pipeline input?False
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-GlobalSecondaryIndexUpdate <GlobalSecondaryIndexUpdate[]>
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.
For more information, see Managing Global Secondary Indexes in the Amazon DynamoDB Developer Guide.
Required?False
Position?Named
Accept pipeline input?False
-ReadCapacity <Int64>
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.
Required?False
Position?Named
Accept pipeline input?False
-StreamSpecification_StreamEnabled <Boolean>
Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.
Required?False
Position?Named
Accept pipeline input?False
-StreamSpecification_StreamViewType <StreamViewType>
When an item in the table is modified, StreamViewType determines what information is written to the stream for this table. Valid values for StreamViewType are:
  • KEYS_ONLY - Only the key attributes of the modified item are written to the stream.
  • NEW_IMAGE - The entire item, as it appears after it was modified, is written to the stream.
  • OLD_IMAGE - The entire item, as it appeared before it was modified, is written to the stream.
  • NEW_AND_OLD_IMAGES - Both the new and the old item images of the item are written to the stream.
Required?False
Position?Named
Accept pipeline input?False
-TableName <String>
The name of the table to be updated.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-WriteCapacity <Int64>
The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException. For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide.
Required?False
Position?Named
Accept pipeline input?False

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String object to this cmdlet for the TableName parameter.

Outputs

This cmdlet returns a TableDescription object. The service call response (type Amazon.DynamoDBv2.Model.UpdateTableResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

PS C:\>Update-DDBTable -TableName "myTable" -ReadCapacity 10 -WriteCapacity 5
Updates the provisioned throughput for the given table.
