AttributeDefinitions |
DynamoDBAttributeDefinitions
|
Required: Yes. A list of AttributeName and AttributeType objects
that describe the key schema for the table and indexes.Update requires: Replacement |
GlobalSecondaryIndexes |
DynamoDBGlobalSecondaryIndexes
|
Required: No. Global secondary indexes to be created on the table. You can create up to 5 global
secondary indexes.
ImportantIf you update a table to include a new global secondary index, AWS CloudFormation initiates
the index creation and then proceeds with the stack update. AWS CloudFormation doesn't wait for
the index to complete creation because the backfilling phase can take a long time,
depending on the size of the table. You cannot use the index or update the table
until the index's status is ACTIVE. You can track its status by using
the DynamoDB DescribeTable command.If you add or delete an index during an update, we recommend that you don't
update any other resources. If your stack fails to update and is rolled back while
adding a new index, you must manually delete the index.
Update requires: Updates are not supported. with the following exceptions:If you update only the provisioned throughput values of global secondary
indexes, you can update the table without
interruption.You can delete or add one global secondary index without interruption. If you do both in the
same update (for example, by changing the index's logical ID), the update
fails. |
KeySchema |
DynamoDBKeySchema
|
Required: Yes. Specifies the attributes that make up the primary key for the table. The
attributes in the KeySchema property must also be defined in the
AttributeDefinitions property.Update requires: Replacement |
LocalSecondaryIndexes |
DynamoDBLocalSecondaryIndexes
|
Required: No. Local secondary indexes to be created on the table. You can create up to 5 local
secondary indexes. Each index is scoped to a given hash key value. The size of each hash
key can be up to 10 gigabytes.Update requires: Replacement |
ProvisionedThroughput |
DynamoDBProvisionedThroughput
|
Required: Yes. Throughput for the specified table, consisting of values for ReadCapacityUnits and
WriteCapacityUnits. For more information about the contents of a provisioned throughput
structure, see DynamoDB Provisioned
Throughput.Update requires: No interruption |
StreamSpecification |
DynamoDBTableStreamSpecification
|
Required: No. The settings for the DynamoDB table stream, which capture changes to items stored in
the table.Update requires: No interruption to the table; however, the stream is replaced. |
TableName |
String
|
Required: No. A name for the table. If you don't specify a name, AWS CloudFormation generates a unique
physical ID and uses that ID for the table name. For more information, see Name Type.ImportantIf you specify a name, you cannot do updates that require this resource to be replaced.
You can still do updates that require no or some interruption. If you must replace the resource, specify a new name.Update requires: Replacement |
