AWS SDK Version 2 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

.NET Framework 4.5
 
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, 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 API to check the table status.

Namespace: Amazon.DynamoDBv2

Syntax

C#
public virtual CreateTableResponse CreateTable(
         String tableName,
         List<KeySchemaElement> keySchema,
         List<AttributeDefinition> attributeDefinitions,
         ProvisionedThroughput provisionedThroughput
)

Parameters

tableName
Type: System.String

The name of the table to create.

keySchema
Type: List<Amazon.DynamoDBv2.Model.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 The partition key of an item is also known as its hash attribute. The term "hash attribute" derives from 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 Specifying the Primary Key in the Amazon DynamoDB Developer Guide.

attributeDefinitions
Type: List<Amazon.DynamoDBv2.Model.AttributeDefinition>

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

provisionedThroughput
Type: Amazon.DynamoDBv2.Model.ProvisionedThroughput

A property of CreateTableRequest used to execute the CreateTable service method.

Return Value
Type: Amazon.DynamoDBv2.Model.CreateTableResponse
The response from the CreateTable service method, as returned by DynamoDB.

Exceptions

ExceptionCondition
InternalServerErrorException An error occurred on the server side.
LimitExceededException The number of concurrent table requests (cumulative number of tables in the CREATING, DELETING or UPDATING state) exceeds the maximum allowed of 10. Also, for tables with secondary indexes, only one of those tables can be in the CREATING state at any point in time. Do not attempt to create more than one such table simultaneously. The total limit of tables in the ACTIVE state is 250.
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.
