# AWS::DynamoDB::GlobalTable
<a name="aws-resource-dynamodb-globaltable"></a>

The `AWS::DynamoDB::GlobalTable` resource enables you to create and manage a Version 2019.11.21 global table. This resource cannot be used to create or manage a Version 2017.11.29 global table. For more information, see [Global tables](https://docs.aws.amazon.com//amazondynamodb/latest/developerguide/GlobalTables.html).

**Important**  
You cannot convert a resource of type `AWS::DynamoDB::Table` into a resource of type `AWS::DynamoDB::GlobalTable` by changing its type in your template. **Doing so might result in the deletion of your DynamoDB table.**  
You can instead use the GlobalTable resource to create a new table in a single Region. This will be billed the same as a single Region table. If you later update the stack to add other Regions then Global Tables pricing will apply.

You should be aware of the following behaviors when working with DynamoDB global tables.
+ The IAM Principal executing the stack operation must have the permissions listed below in all regions where you plan to have a global table replica. The IAM Principal's permissions should not have restrictions based on IP source address. Some global tables operations (for example, adding a replica) are asynchronous, and require that the IAM Principal is valid until they complete. You should not delete the Principal (user or IAM role) until CloudFormation has finished updating your stack.

  +  `dynamodb:UpdateTimeToLive` 
  +  `iam:CreateServiceLinkedRole` 
  +  `kms:CreateGrant` 
  +  `kms:DescribeKey` 
+ When using provisioned billing mode, CloudFormation will create an auto scaling policy on each of your replicas to control their write capacities. You must configure this policy using the `WriteProvisionedThroughputSettings` property. CloudFormation will ensure that all replicas have the same write capacity auto scaling property. You cannot directly specify a value for write capacity for a global table.
+ If your table uses provisioned capacity, you must configure auto scaling directly in the `AWS::DynamoDB::GlobalTable` resource. You should not configure additional auto scaling policies on any of the table replicas or global secondary indexes, either via API or via `AWS::ApplicationAutoScaling::ScalableTarget` or `AWS::ApplicationAutoScaling::ScalingPolicy`. Doing so might result in unexpected behavior and is unsupported.
+ In AWS CloudFormation, each global table is controlled by a single stack, in a single region, regardless of the number of replicas. When you deploy your template, CloudFormation will create/update all replicas as part of a single stack operation. You should not deploy the same `AWS::DynamoDB::GlobalTable` resource in multiple regions. Doing so will result in errors, and is unsupported. If you deploy your application template in multiple regions, you can use conditions to only create the resource in a single region. Alternatively, you can choose to define your `AWS::DynamoDB::GlobalTable` resources in a stack separate from your application stack, and make sure it is only deployed to a single region.

Specifies how you are charged for read and write throughput and how you manage capacity. Valid values are:  
+  `PAY_PER_REQUEST` 
+  `PROVISIONED` 
All replicas in your global table will have the same billing mode. If you use `PROVISIONED` billing mode, you must provide an auto scaling configuration via the `WriteProvisionedThroughputSettings` property. The default value of this property is `PROVISIONED`.  
*Required*: No  
*Type*: String  
*Allowed values*: `PROVISIONED | PAY_PER_REQUEST`

Local secondary indexes to be created on the table. You can create up to five 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. Each replica in your global table will have the same local secondary index settings.  
*Required*: No  
*Type*: Array of [LocalSecondaryIndex](aws-properties-dynamodb-globaltable-localsecondaryindex.md)  
*Update requires*: [Some interruptions](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-some-interrupt)

`MultiRegionConsistency`  <a name="cfn-dynamodb-globaltable-multiregionconsistency"></a>
Specifies the consistency mode for a new global table.  
You can specify one of the following consistency modes:  
+ `EVENTUAL`: Configures a new global table for multi-Region eventual consistency (MREC).
+ `STRONG`: Configures a new global table for multi-Region strong consistency (MRSC).
If you don't specify this field, the global table consistency mode defaults to `EVENTUAL`. For more information about global tables consistency modes, see [ Consistency modes](https://docs.aws.amazon.com/V2globaltables_HowItWorks.html#V2globaltables_HowItWorks.consistency-modes) in DynamoDB developer guide.

`Replicas`  <a name="cfn-dynamodb-globaltable-replicas"></a>
Specifies the list of replicas for your global table. The list must contain at least one element, the region where the stack defining the global table is deployed. For example, if you define your table in a stack deployed to us-east-1, you must have an entry in `Replicas` with the region us-east-1. You cannot remove the replica in the stack region.  
Adding a replica might take a few minutes for an empty table, or up to several hours for large tables. If you want to add or remove a replica, we recommend submitting an `UpdateStack` operation containing only that change.  
If you add or delete a replica 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 replica, you might need to manually delete the replica.
You can create a new global table with as many replicas as needed. You can add or remove replicas after table creation, but you can only add or remove a single replica in each update. For Multi-Region Strong Consistency (MRSC), you can add or remove up to 3 replicas, or 2 replicas plus a witness Region.

*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`StreamSpecification`  <a name="cfn-dynamodb-globaltable-streamspecification"></a>
Specifies the streams settings on your global table. You must provide a value for this property if your global table contains more than one replica. You can only change the streams settings if your global table has only one replica. For Multi-Region Strong Consistency (MRSC), you do not need to provide a value for this property and can change the settings at any time.  
*Required*: No  
*Type*: [StreamSpecification](aws-properties-dynamodb-globaltable-streamspecification.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`TableName`  <a name="cfn-dynamodb-globaltable-tablename"></a>
A name for the global table. If you don't specify a name, AWS CloudFormation generates a unique ID and uses that ID as the table name. For more information, see [Name type](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-name.html).

`SeedCapacity`  <a name="cfn-dynamodb-globaltable-capacityautoscalingsettings-seedcapacity"></a>
When switching billing mode from `PAY_PER_REQUEST` to `PROVISIONED`, DynamoDB requires you to specify read and write capacity unit values for the table and for each global secondary index. These values will be applied to all replicas. The table will use these provisioned values until CloudFormation creates the autoscaling policies you configured in your template. CloudFormation cannot determine what capacity the table and its global secondary indexes will require in this time period, since they are application-dependent.  
If you want to switch a table's billing mode from `PAY_PER_REQUEST` to `PROVISIONED`, you must specify a value for this property for each autoscaled resource. If you specify different values for the same resource in different regions, CloudFormation will use the highest value found in either the `SeedCapacity` or `ReadCapacityUnits` properties. For example, if your global secondary index `myGSI` has a `SeedCapacity` of 10 in us-east-1 and a fixed `ReadCapacityUnits` of 20 in eu-west-1, CloudFormation will initially set the read capacity for `myGSI` to 20. Note that if you disable `ScaleIn` for `myGSI` in us-east-1, its read capacity units might not be set back to 10.  
You must also specify a value for `SeedCapacity` when you plan to switch a table's billing mode from `PROVISIONED` to `PAY_PER_REQUEST`, because CloudFormation might need to roll back the operation (reverting the billing mode to `PROVISIONED`) and this cannot succeed without specifying a value for `SeedCapacity`.

# AWS::DynamoDB::GlobalTable ResourcePolicy
<a name="aws-properties-dynamodb-globaltable-resourcepolicy"></a>

Creates or updates a resource-based policy document that contains the permissions for DynamoDB resources, such as a table, its indexes, and stream. Resource-based policies let you define access permissions by specifying who has access to each resource, and the actions they are allowed to perform on each resource.

In a CloudFormation template, you can provide the policy in JSON or YAML format because CloudFormation converts YAML to JSON before submitting it to DynamoDB. For more information about resource-based policies, see [Using resource-based policies for DynamoDB](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/access-control-resource-based.html) and [Resource-based policy examples](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/rbac-examples.html).

While defining resource-based policies in your CloudFormation templates, the following considerations apply:
+ The maximum size supported for a resource-based policy document in JSON format is 20 KB. DynamoDB counts whitespaces when calculating the size of a policy against this limit. 
+ Resource-based policies don't support [drift detection](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift.html#). If you update a policy outside of the CloudFormation stack template, you'll need to update the CloudFormation stack with the changes.
+ Resource-based policies don't support out-of-band changes. If you add, update, or delete a policy outside of the CloudFormation template, the change won't be overwritten if there are no changes to the policy within the template.

  For example, say that your template contains a resource-based policy, which you later update outside of the template. If you don't make any changes to the policy in the template, the updated policy in DynamoDB won’t be synced with the policy in the template.

  Conversely, say that your template doesn’t contain a resource-based policy, but you add a policy outside of the template. This policy won’t be removed from DynamoDB as long as you don’t add it to the template. When you add a policy to the template and update the stack, the existing policy in DynamoDB will be updated to match the one defined in the template.
+ Within a resource-based policy, if the action for a DynamoDB service-linked role (SLR) to replicate data for a global table is denied, adding or deleting a replica will fail with an error.
+ The [AWS::DynamoDB::GlobalTable](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-dynamodb-globaltable.html) resource doesn't support creating a replica in the same stack update in Regions other than the Region where you deploy the stack update.

For a full list of all considerations, see [Resource-based policy considerations](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/rbac-considerations.html).

For more information about resource-based policies, see [Using resource-based policies for DynamoDB](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/access-control-resource-based.html) and [Resource-based policy examples](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/rbac-examples.html).  
*Required*: Yes  
*Type*: Json

## Examples
<a name="aws-properties-dynamodb-globaltable-resourcepolicy--examples"></a>

### Attaching a resource-based policy to a DynamoDB table created using the `AWS::DynamoDB::GlobalTable` resource.
<a name="aws-properties-dynamodb-globaltable-resourcepolicy--examples--Attaching_a_resource-based_policy_to_a_table_created_using_the_::DynamoDB::GlobalTable_resource."></a>

The following CloudFormation template creates a table with the [AWS::DynamoDB::GlobalTable](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-dynamodb-globaltable.html) resource and attaches a resource-based policy to the table and its stream. This policy allows the user `foobar` to perform the [GetItem](https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_GetItem.html) operation on the table. Additionally, the following template enables a stream and then attaches a resource-based policy to the stream. The resource-based policy for the stream allows the user `foobar` to perform the [GetRecords](https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_streams_GetRecords.html), [GetShardIterator](https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_streams_GetShardIterator.html), and [DescribeStream](https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_streams_DescribeStream.html) operations on the stream.

**Important**  
If you enable a stream within a CloudFormation template and also define a policy for the stream, the policy is attached to the stream only after the stream is enabled, but before the stack update is complete.

+ `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.
+ `NEW_AND_OLD_IMAGES` - Both the new and the old item images of the item are written to the stream.
*Required*: Yes  
*Type*: String  
*Allowed values*: `NEW_IMAGE | OLD_IMAGE | NEW_AND_OLD_IMAGES | KEYS_ONLY`
