Class CreateTableRequest

Namespace
Amazon.DynamoDBv2.Model
Assembly
AWSSDK.DynamoDBv2.dll

Container for the parameters to the CreateTable operation. The

CreateTable
operation adds a new table to your account. In an Amazon Web Services 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, DynamoDB immediately returns a response with a
TableStatus
of
CREATING
. After the table is created, DynamoDB sets the
TableStatus
to
ACTIVE
. You can perform read and write operations only on an
ACTIVE
table.

You can optionally define secondary indexes on the new table, as part of the

CreateTable
operation. If you want to create multiple tables with secondary indexes on them, you must create the tables sequentially. Only one table with secondary indexes can be in the
CREATING
state at any given time.

You can use the

DescribeTable
action to check the table status.

Constructors

CreateTableRequest()

Empty constructor used to set properties independently even when a simple constructor is available

public CreateTableRequest()

CreateTableRequest(string, List<KeySchemaElement>)

Instantiates CreateTableRequest with the parameterized properties

public CreateTableRequest(string tableName, List<KeySchemaElement> keySchema)

Parameters

tableName string

The name of the table to create.

keySchema List<KeySchemaElement>

Specifies the attributes that make up the primary key for a table or an index. The attributes in

KeySchema
must also be defined in the
AttributeDefinitions
array. For more information, see Data Model in the Amazon DynamoDB Developer Guide. Each
KeySchemaElement
in the array is composed of:
  • AttributeName
    - The name of this key attribute.
  • KeyType
    - The role that the key attribute will assume:
    • HASH
      - partition key
    • RANGE
      - sort key
note

The partition key of an item is also known as its hash attribute. The term "hash attribute" derives from the DynamoDB usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values. The sort key of an item is also known as its range attribute. The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

For a simple primary key (partition key), you must provide exactly one element with a
KeyType
of
HASH
. For a composite primary key (partition key and sort key), you must provide exactly two elements, in this order: The first element must have a
KeyType
of
HASH
, and the second element must have a
KeyType
of
RANGE
. For more information, see Working with Tables in the Amazon DynamoDB Developer Guide.

attributeDefinitions List<AttributeDefinition>

An array of attributes that describe the key schema for the table and indexes.

provisionedThroughput ProvisionedThroughput

Represents the provisioned throughput settings for a specified table or index. The settings can be modified using the

UpdateTable
operation. If you set BillingMode as
PROVISIONED
, you must specify this property. If you set BillingMode as
PAY_PER_REQUEST
, you cannot specify this property. For current minimum and maximum provisioned throughput values, see Service, Account, and Table Quotas in the Amazon DynamoDB Developer Guide.

Properties

AttributeDefinitions

Gets and sets the property AttributeDefinitions.

An array of attributes that describe the key schema for the table and indexes.

public List<AttributeDefinition> AttributeDefinitions { get; set; }

Property Value

List<AttributeDefinition>

BillingMode

Gets and sets the property 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.
public BillingMode BillingMode { get; set; }

Property Value

BillingMode

GlobalSecondaryIndexes

Gets and sets the property GlobalSecondaryIndexes.

One or more global secondary indexes (the maximum is 20) to be created on the table. Each global secondary index in the array includes the following:

  • IndexName
    - The name of the global secondary index. Must be unique only for this table.
  • KeySchema
    - Specifies the key schema for the global secondary index.
  • Projection
    - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:
    • ProjectionType
      - One of the following:
      • KEYS_ONLY
        - Only the index and primary keys are projected into the index.
      • INCLUDE
