Amazon DynamoDB Construct Library

Here is a minimal deployable DynamoDB table definition:

table := dynamodb.NewTable(this, jsii.String("Table"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
})

Importing existing tables

To import an existing table into your CDK application, use the Table.fromTableName, Table.fromTableArn or Table.fromTableAttributes factory method. This method accepts table name or table ARN which describes the properties of an already existing table:

var user user

table := dynamodb.table.fromTableArn(this, jsii.String("ImportedTable"), jsii.String("arn:aws:dynamodb:us-east-1:111111111:table/my-table"))
// now you can just call methods on the table
table.grantReadWriteData(user)

If you intend to use the tableStreamArn (including indirectly, for example by creating an @aws-cdk/aws-lambda-event-source.DynamoEventSource on the imported table), you must use the Table.fromTableAttributes method and the tableStreamArn property must be populated.

Keys

When a table is defined, you must define it's schema using the partitionKey (required) and sortKey (optional) properties.

Billing Mode

DynamoDB supports two billing modes:

  • PROVISIONED - the default mode where the table and global secondary indexes have configured read and write capacity.
  • PAY_PER_REQUEST - on-demand pricing and scaling. You only pay for what you use and there is no read and write capacity for the table or its global secondary indexes.
table := dynamodb.NewTable(this, jsii.String("Table"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	billingMode: dynamodb.billingMode_PAY_PER_REQUEST,
})

Table Class

DynamoDB supports two table classes:

  • STANDARD - the default mode, and is recommended for the vast majority of workloads.
  • STANDARD_INFREQUENT_ACCESS - optimized for tables where storage is the dominant cost.
table := dynamodb.NewTable(this, jsii.String("Table"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	tableClass: dynamodb.tableClass_STANDARD_INFREQUENT_ACCESS,
})

Configure AutoScaling for your table

You can have DynamoDB automatically raise and lower the read and write capacities of your table by setting up autoscaling. You can use this to either keep your tables at a desired utilization level, or by scaling up and down at pre-configured times of the day:

Auto-scaling is only relevant for tables with the billing mode, PROVISIONED.

readScaling := table.autoScaleReadCapacity(&enableScalingProps{
	minCapacity: jsii.Number(1),
	maxCapacity: jsii.Number(50),
})

readScaling.scaleOnUtilization(&utilizationScalingProps{
	targetUtilizationPercent: jsii.Number(50),
})

readScaling.scaleOnSchedule(jsii.String("ScaleUpInTheMorning"), &scalingSchedule{
	schedule: appscaling.schedule.cron(&cronOptions{
		hour: jsii.String("8"),
		minute: jsii.String("0"),
	}),
	minCapacity: jsii.Number(20),
})

readScaling.scaleOnSchedule(jsii.String("ScaleDownAtNight"), &scalingSchedule{
	schedule: appscaling.*schedule.cron(&cronOptions{
		hour: jsii.String("20"),
		minute: jsii.String("0"),
	}),
	maxCapacity: jsii.Number(20),
})

Further reading: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AutoScaling.html https://aws.amazon.com/blogs/database/how-to-use-aws-cloudformation-to-configure-auto-scaling-for-amazon-dynamodb-tables-and-indexes/

Amazon DynamoDB Global Tables

You can create DynamoDB Global Tables by setting the replicationRegions property on a Table:

globalTable := dynamodb.NewTable(this, jsii.String("Table"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	replicationRegions: []*string{
		jsii.String("us-east-1"),
		jsii.String("us-east-2"),
		jsii.String("us-west-2"),
	},
})

When doing so, a CloudFormation Custom Resource will be added to the stack in order to create the replica tables in the selected regions.

The default billing mode for Global Tables is PAY_PER_REQUEST. If you want to use PROVISIONED, you have to make sure write auto-scaling is enabled for that Table:

globalTable := dynamodb.NewTable(this, jsii.String("Table"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	replicationRegions: []*string{
		jsii.String("us-east-1"),
		jsii.String("us-east-2"),
		jsii.String("us-west-2"),
	},
	billingMode: dynamodb.billingMode_PROVISIONED,
})

globalTable.autoScaleWriteCapacity(&enableScalingProps{
	minCapacity: jsii.Number(1),
	maxCapacity: jsii.Number(10),
}).scaleOnUtilization(&utilizationScalingProps{
	targetUtilizationPercent: jsii.Number(75),
})

When adding a replica region for a large table, you might want to increase the timeout for the replication operation:

globalTable := dynamodb.NewTable(this, jsii.String("Table"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	replicationRegions: []*string{
		jsii.String("us-east-1"),
		jsii.String("us-east-2"),
		jsii.String("us-west-2"),
	},
	replicationTimeout: awscdk.Duration.hours(jsii.Number(2)),
})

Encryption

All user data stored in Amazon DynamoDB is fully encrypted at rest. When creating a new table, you can choose to encrypt using the following customer master keys (CMK) to encrypt your table:

  • AWS owned CMK - By default, all tables are encrypted under an AWS owned customer master key (CMK) in the DynamoDB service account (no additional charges apply).
  • AWS managed CMK - AWS KMS keys (one per region) are created in your account, managed, and used on your behalf by AWS DynamoDB (AWS KMS charges apply).
  • Customer managed CMK - You have full control over the KMS key used to encrypt the DynamoDB Table (AWS KMS charges apply).

Creating a Table encrypted with a customer managed CMK:

table := dynamodb.NewTable(this, jsii.String("MyTable"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	encryption: dynamodb.tableEncryption_CUSTOMER_MANAGED,
})

// You can access the CMK that was added to the stack on your behalf by the Table construct via:
tableEncryptionKey := table.encryptionKey

You can also supply your own key:

import kms "github.com/aws/aws-cdk-go/awscdk"


encryptionKey := kms.NewKey(this, jsii.String("Key"), &keyProps{
	enableKeyRotation: jsii.Boolean(true),
})
table := dynamodb.NewTable(this, jsii.String("MyTable"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	encryption: dynamodb.tableEncryption_CUSTOMER_MANAGED,
	encryptionKey: encryptionKey,
})

In order to use the AWS managed CMK instead, change the code to:

table := dynamodb.NewTable(this, jsii.String("MyTable"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	encryption: dynamodb.tableEncryption_AWS_MANAGED,
})

Get schema of table or secondary indexes

To get the partition key and sort key of the table or indexes you have configured:

var table table

schema := table.schema()
partitionKey := schema.partitionKey
sortKey := schema.sortKey

Kinesis Stream

A Kinesis Data Stream can be configured on the DynamoDB table to capture item-level changes.

import kinesis "github.com/aws/aws-cdk-go/awscdk"


stream := kinesis.NewStream(this, jsii.String("Stream"))

table := dynamodb.NewTable(this, jsii.String("Table"), &tableProps{
	partitionKey: &attribute{
		name: jsii.String("id"),
		type: dynamodb.attributeType_STRING,
	},
	kinesisStream: stream,
})

A CloudFormation `AWS::DynamoDB::GlobalTable`.

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.

> 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:CreateTable` - `dynamodb:UpdateTable` - `dynamodb:DeleteTable` - `dynamodb:DescribeContinuousBackups` - `dynamodb:DescribeContributorInsights` - `dynamodb:DescribeTable` - `dynamodb:DescribeTableReplicaAutoScaling` - `dynamodb:DescribeTimeToLive` - `dynamodb:ListTables` - `dynamodb:UpdateTimeToLive` - `dynamodb:UpdateContributorInsights` - `dynamodb:UpdateContinuousBackups` - `dynamodb:ListTagsOfResource` - `dynamodb:TableClass` - `dynamodb:TagResource` - `dynamodb:UntagResource` - `dynamodb:BatchWriteItem` - `dynamodb:CreateTableReplica` - `dynamodb:DeleteItem` - `dynamodb:DeleteTableReplica` - `dynamodb:DisableKinesisStreamingDestination` - `dynamodb:EnableKinesisStreamingDestination` - `dynamodb:GetItem` - `dynamodb:PutItem` - `dynamodb:Query` - `dynamodb:Scan` - `dynamodb:UpdateItem` - `dynamodb:DescribeTableReplicaAutoScaling` - `dynamodb:UpdateTableReplicaAutoScaling` - `iam:CreateServiceLinkedRole` - `kms:CreateGrant` - `kms:DescribeKey` - `application-autoscaling:DeleteScalingPolicy` - `application-autoscaling:DeleteScheduledAction` - `application-autoscaling:DeregisterScalableTarget` - `application-autoscaling:DescribeScalingPolicies` - `application-autoscaling:DescribeScalableTargets` - `application-autoscaling:PutScalingPolicy` - `application-autoscaling:PutScheduledAction` - `application-autoscaling:RegisterScalableTarget` - 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.

	KeyType *string `field:"required" json:"keyType" yaml:"keyType"`
}

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.

A CloudFormation `AWS::DynamoDB::Table`.

The `AWS::DynamoDB::Table` resource creates a DynamoDB table. For more information, see [CreateTable](https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_CreateTable.html) in the *Amazon DynamoDB API Reference* .

You should be aware of the following behaviors when working with DynamoDB tables:

- AWS CloudFormation typically creates DynamoDB tables in parallel. However, if your template includes multiple DynamoDB tables with indexes, you must declare dependencies so that the tables are created sequentially. Amazon DynamoDB limits the number of tables with secondary indexes that are in the creating state. If you create multiple tables with indexes at the same time, DynamoDB returns an error and the stack operation fails. For an example, see [DynamoDB Table with a DependsOn Attribute](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-dynamodb-table.html#aws-resource-dynamodb-table--examples--DynamoDB_Table_with_a_DependsOn_Attribute) .

	KeyType *string `field:"required" json:"keyType" yaml:"keyType"`
}

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.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
