ServiceResource / Action / create_table

create_table#

DynamoDB.ServiceResource.create_table(**kwargs)#

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.

Parameters:

AttributeDefinitions (list) –
[REQUIRED]

An array of attributes that describe the key schema for the table and indexes.
- (dict) –
  
  Represents an attribute for describing the schema for the table and indexes.
  - AttributeName (string) – [REQUIRED]
    
    A name for the attribute.
  - AttributeType (string) – [REQUIRED]
    
    The data type for the attribute, where:
    - S - the attribute is of type String
    - N - the attribute is of type Number
    - B - the attribute is of type Binary
TableName (string) –
[REQUIRED]

The name of the table to create. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.
KeySchema (list) –
[REQUIRED]

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.
- (dict) –
  
  Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.
  
  A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.
  
  A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.
  - AttributeName (string) – [REQUIRED]
    
    The name of a key attribute.
  - KeyType (string) – [REQUIRED]
    
    The role that this key attribute will assume:
    - HASH - partition key
    - RANGE - sort key

    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.
LocalSecondaryIndexes (list) –

Each local secondary index in the array includes the following:
- IndexName - The name of the local secondary index. Must be unique only for this table.
- KeySchema - Specifies the key schema for the local secondary index. The key schema must begin with the same partition key as the table.

  - NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes, summed across all of the secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
- (dict) –

ResourcePolicy (string) –
An Amazon Web Services resource-based policy document in JSON format that will be attached to the table.

When you attach a resource-based policy while creating a table, the policy application is strongly consistent.

The maximum size supported for a resource-based policy document is 20 KB. DynamoDB counts whitespaces when calculating the size of a policy against this limit. For a full list of all considerations that apply for resource-based policies, see Resource-based policy considerations.

Note
You need to specify the CreateTable and PutResourcePolicy IAM actions for authorizing a user to create a table with a resource-based policy.

Sets 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.
- MaxReadRequestUnits (integer) –
  
  Maximum number of read request units for the specified table.
  
  To specify a maximum OnDemandThroughput on your table, set the value of MaxReadRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxReadRequestUnits to -1.
- MaxWriteRequestUnits (integer) –
