Synopsis

Calls the Amazon DynamoDB CreateTable API operation.

Syntax

New-DDBTable
-TableName <String>
-Schema <TableSchema>
-ReadCapacity <Int64>
-WriteCapacity <Int64>
-BillingMode <BillingMode>
-Force <SwitchParameter>
-Select <String>
-ClientConfig <AmazonDynamoDBConfig>

Description

The CreateTable operation adds a new table to your account. In an AWS account, table names must be unique within each region. That is, you can have two tables with same name if you create the tables in different regions.CreateTable is an asynchronous operation. Upon receiving a CreateTable request, Amazon DynamoDB immediately returns a response with a TableStatus of CREATING . After the table is created, Amazon DynamoDB sets the TableStatus to ACTIVE . You can perform read and write operations only on an ACTIVE table. If you want to create multiple tables with local secondary indexes on them, you must create them sequentially. Only one table with local secondary indexes can be in the CREATING state at any given time.You can use the DescribeTable API to check the table status.

Parameters

-BillingMode <BillingMode>
Controls how you are charged for read and write throughput and how you manage capacity. This setting can be changed later.
  • 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.

Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-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?True (ByPropertyName)
-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?True (ByValue, ByPropertyName)
-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.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?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-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.

Outputs

Amazon.DynamoDBv2.Model.TableDescription or Amazon.DynamoDBv2.Model.CreateTableResponse
This cmdlet returns aN Amazon.DynamoDBv2.Model.TableDescription object. The service call response (type Amazon.DynamoDBv2.Model.CreateTableResponse) can be returned by specifying '-Select *'.

Examples

Example 1

$schema = New-DDBTableSchema
$schema | Add-DDBKeySchema -KeyName "ForumName" -KeyDataType "S"
$schema | Add-DDBKeySchema -KeyName "Subject" -KeyType RANGE -KeyDataType "S"
$schema | New-DDBTable -TableName "Thread" -ReadCapacity 10 -WriteCapacity 5

AttributeDefinitions   : {ForumName, Subject}
TableName              : Thread
KeySchema              : {ForumName, Subject}
TableStatus            : CREATING
CreationDateTime       : 10/28/2013 4:39:49 PM
ProvisionedThroughput  : Amazon.DynamoDBv2.Model.ProvisionedThroughputDescription
TableSizeBytes         : 0
ItemCount              : 0
LocalSecondaryIndexes  : {}
This example creates a table named Thread that has a primary key consisting of 'ForumName' (key type hash) and 'Subject' (key type range). The schema used to construct the table can be piped into each cmdlet as shown or specified using the -Schema parameter.

Example 2

$schema = New-DDBTableSchema
$schema | Add-DDBKeySchema -KeyName "ForumName" -KeyDataType "S"
$schema | Add-DDBKeySchema -KeyName "Subject" -KeyDataType "S"
$schema | Add-DDBIndexSchema -IndexName "LastPostIndex" -RangeKeyName "LastPostDateTime" -RangeKeyDataType "S" -ProjectionType "keys_only"
$schema | New-DDBTable -TableName "Thread" -ReadCapacity 10 -WriteCapacity 5

AttributeDefinitions   : {ForumName, LastPostDateTime, Subject}
TableName              : Thread
KeySchema              : {ForumName, Subject}
TableStatus            : CREATING
CreationDateTime       : 10/28/2013 4:39:49 PM
ProvisionedThroughput  : Amazon.DynamoDBv2.Model.ProvisionedThroughputDescription
TableSizeBytes         : 0
ItemCount              : 0
LocalSecondaryIndexes  : {LastPostIndex}
This example creates a table named Thread that has a primary key consisting of 'ForumName' (key type hash) and 'Subject' (key type range). A local secondary index is also defined. The key of the local secondary index will be set automatically from the primary hash key on the table (ForumName). The schema used to construct the table can be piped into each cmdlet as shown or specified using the -Schema parameter.

Example 3

New-DDBTableSchema |
  Add-DDBKeySchema -KeyName "ForumName" -KeyDataType "S" |
  Add-DDBKeySchema -KeyName "Subject" -KeyDataType "S" |
  Add-DDBIndexSchema -IndexName "LastPostIndex" `
                     -RangeKeyName "LastPostDateTime" `
                     -RangeKeyDataType "S" `
                     -ProjectionType "keys_only" |
  New-DDBTable -TableName "Thread" -ReadCapacity 10 -WriteCapacity 5

AttributeDefinitions   : {ForumName, LastPostDateTime, Subject}
TableName              : Thread
KeySchema              : {ForumName, Subject}
TableStatus            : CREATING
CreationDateTime       : 10/28/2013 4:39:49 PM
ProvisionedThroughput  : Amazon.DynamoDBv2.Model.ProvisionedThroughputDescription
TableSizeBytes         : 0
ItemCount              : 0
LocalSecondaryIndexes  : {LastPostIndex}
This example shows how to use a single pipeline to create a table named Thread that has a primary key consisting of 'ForumName' (key type hash) and 'Subject' (key type range) and a local secondary index. The Add-DDBKeySchema and Add-DDBIndexSchema create a new TableSchema object for you if one is not supplied from the pipeline or the -Schema parameter.
