create-table

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, 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.

Options

--attribute-definitions (list)

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

Shorthand Syntax:

AttributeName=string,AttributeType=string ...

JSON Syntax:

[
  {
    "AttributeName": "string",
    "AttributeType": "S"|"N"|"B"
  }
  ...
]

--table-name (string)

The name of the table to create.

--key-schema (list)

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 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 .

Shorthand Syntax:

AttributeName=string,KeyType=string ...

JSON Syntax:

[
  {
    "AttributeName": "string",
    "KeyType": "HASH"|"RANGE"
  }
  ...
]

--local-secondary-indexes (list)

One or more local secondary indexes (the maximum is five) to be created on the table. Each index is scoped to a given partition key value. There is a 10 GB size limit per partition key value; otherwise, the size of a local secondary index is unconstrained.

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.
  • 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 - Only the specified table attributes are projected into the index. The list of projected attributes are in NonKeyAttributes .
      • ALL - All of the table attributes are projected into the index.
    • 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 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

Shorthand Syntax:

IndexName=string,KeySchema=[{AttributeName=string,KeyType=string},{AttributeName=string,KeyType=string}],Projection={ProjectionType=string,NonKeyAttributes=[string,string]} ...

  • 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 - Only the specified table attributes are projected into the index. The list of projected attributes are in NonKeyAttributes .
      • ALL - All of the table attributes are projected into the index.

The total count of attributes provided in NonKeyAttributes , summed across all of the secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
  • ProvisionedThroughput - The provisioned throughput settings for the global secondary index, consisting of read and write capacity units.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

For more information about primary keys, see Primary Key in the Amazon DynamoDB Developer Guide .

(structure)

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)

The name of a key attribute.

KeyType -> (string)

The role that this key attribute will assume:

  • HASH - partition key
  • RANGE - sort key

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.
