Amazon Kinesis Construct Library

Amazon Kinesis provides collection and processing of large streams of data records in real time. Kinesis data streams can be used for rapid and continuous data intake and aggregation.

Table Of Contents

Streams

Amazon Kinesis Data Streams ingests a large amount of data in real time, durably stores the data, and makes the data available for consumption.

Using the CDK, a new Kinesis stream can be created as part of the stack using the construct's constructor. You may specify the streamName to give your own identifier to the stream. If not, CloudFormation will generate a name.

kinesis.NewStream(this, jsii.String("MyFirstStream"), &StreamProps{
	StreamName: jsii.String("my-awesome-stream"),
})

You can also specify properties such as shardCount to indicate how many shards the stream should choose and a retentionPeriod to specify how long the data in the shards should remain accessible. Read more at Creating and Managing Streams

kinesis.NewStream(this, jsii.String("MyFirstStream"), &StreamProps{
	StreamName: jsii.String("my-awesome-stream"),
	ShardCount: jsii.Number(3),
	RetentionPeriod: awscdk.Duration_Hours(jsii.Number(48)),
})
Encryption

Stream encryption enables server-side encryption using an AWS KMS key for a specified stream.

Encryption is enabled by default on your stream with the master key owned by Kinesis Data Streams in regions where it is supported.

kinesis.NewStream(this, jsii.String("MyEncryptedStream"))

You can enable encryption on your stream with a user-managed key by specifying the encryption property. A KMS key will be created for you and associated with the stream.

kinesis.NewStream(this, jsii.String("MyEncryptedStream"), &StreamProps{
	Encryption: kinesis.StreamEncryption_KMS,
})

You can also supply your own external KMS key to use for stream encryption by specifying the encryptionKey property.

key := kms.NewKey(this, jsii.String("MyKey"))

kinesis.NewStream(this, jsii.String("MyEncryptedStream"), &StreamProps{
	Encryption: kinesis.StreamEncryption_KMS,
	EncryptionKey: key,
})
Import

Any Kinesis stream that has been created outside the stack can be imported into your CDK app.

Streams can be imported by their ARN via the Stream.fromStreamArn() API

importedStream := kinesis.Stream_FromStreamArn(this, jsii.String("ImportedStream"), jsii.String("arn:aws:kinesis:us-east-2:123456789012:stream/f3j09j2230j"))

Encrypted Streams can also be imported by their attributes via the Stream.fromStreamAttributes() API

importedStream := kinesis.Stream_FromStreamAttributes(this, jsii.String("ImportedEncryptedStream"), &StreamAttributes{
	StreamArn: jsii.String("arn:aws:kinesis:us-east-2:123456789012:stream/f3j09j2230j"),
	EncryptionKey: kms.Key_FromKeyArn(this, jsii.String("key"), jsii.String("arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012")),
})
Permission Grants

IAM roles, users or groups which need to be able to work with Amazon Kinesis streams at runtime should be granted IAM permissions.

Any object that implements the IGrantable interface (has an associated principal) can be granted permissions by calling:

  • grantRead(principal) - grants the principal read access
  • grantWrite(principal) - grants the principal write permissions to a Stream
  • grantReadWrite(principal) - grants principal read and write permissions
Read Permissions

Grant read access to a stream by calling the grantRead() API. If the stream has an encryption key, read permissions will also be granted to the key.

lambdaRole := iam.NewRole(this, jsii.String("Role"), &RoleProps{
	AssumedBy: iam.NewServicePrincipal(jsii.String("lambda.amazonaws.com")),
	Description: jsii.String("Example role..."),
})

stream := kinesis.NewStream(this, jsii.String("MyEncryptedStream"), &StreamProps{
	Encryption: kinesis.StreamEncryption_KMS,
})

// give lambda permissions to read stream
stream.grantRead(lambdaRole)

The following read permissions are provided to a service principal by the grantRead() API:

  • kinesis:DescribeStreamSummary
  • kinesis:GetRecords
  • kinesis:GetShardIterator
  • kinesis:ListShards
  • kinesis:SubscribeToShard
Write Permissions

Grant write permissions to a stream is provided by calling the grantWrite() API. If the stream has an encryption key, write permissions will also be granted to the key.

lambdaRole := iam.NewRole(this, jsii.String("Role"), &RoleProps{
	AssumedBy: iam.NewServicePrincipal(jsii.String("lambda.amazonaws.com")),
	Description: jsii.String("Example role..."),
})

stream := kinesis.NewStream(this, jsii.String("MyEncryptedStream"), &StreamProps{
	Encryption: kinesis.StreamEncryption_KMS,
})

// give lambda permissions to write to stream
stream.grantWrite(lambdaRole)

The following write permissions are provided to a service principal by the grantWrite() API:

  • kinesis:ListShards
  • kinesis:PutRecord
  • kinesis:PutRecords
Custom Permissions

You can add any set of permissions to a stream by calling the grant() API.

user := iam.NewUser(this, jsii.String("MyUser"))

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

// give my user permissions to list shards
stream.grant(user, jsii.String("kinesis:ListShards"))
Metrics

You can use common metrics from your stream to create alarms and/or dashboards. The stream.metric('MetricName') method creates a metric with the stream namespace and dimension. You can also use pre-define methods like stream.metricGetRecordsSuccess(). To find out more about Kinesis metrics check Monitoring the Amazon Kinesis Data Streams Service with Amazon CloudWatch.

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

// Using base metric method passing the metric name
stream.metric(jsii.String("GetRecords.Success"))

// using pre-defined metric method
stream.metricGetRecordsSuccess()

// using pre-defined and overriding the statistic
stream.metricGetRecordsSuccess(&MetricOptions{
	Statistic: jsii.String("Maximum"),
})

Functions

func CfnStreamConsumer_CFN_RESOURCE_TYPE_NAME 

func CfnStreamConsumer_CFN_RESOURCE_TYPE_NAME() *string

func CfnStreamConsumer_IsCfnElement 

func CfnStreamConsumer_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnStreamConsumer_IsCfnResource 

func CfnStreamConsumer_IsCfnResource(construct constructs.IConstruct) *bool

Check whether the given construct is a CfnResource.

func CfnStreamConsumer_IsConstruct 

func CfnStreamConsumer_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func CfnStream_CFN_RESOURCE_TYPE_NAME 

func CfnStream_CFN_RESOURCE_TYPE_NAME() *string

func CfnStream_IsCfnElement 

func CfnStream_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnStream_IsConstruct 

func CfnStream_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func NewCfnStreamConsumer_Override

func NewStream_Override 

func NewStream_Override(s Stream, scope constructs.Construct, id *string, props *StreamProps)

func Stream_IsConstruct 

func Stream_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func Stream_IsOwnedResource added in v2.32.0 

func Stream_IsOwnedResource(construct constructs.IConstruct) *bool

Returns true if the construct was created by CDK, and false otherwise.

Use the AWS CloudFormation `AWS::Kinesis::StreamConsumer` resource to register a consumer with a Kinesis data stream.

The consumer you register can then call [SubscribeToShard](https://docs.aws.amazon.com/kinesis/latest/APIReference/API_SubscribeToShard.html) to receive data from the stream using enhanced fan-out, at a rate of up to 2 MiB per second for every shard you subscribe to. This rate is unaffected by the total number of consumers that read from the same stream.

You can register up to five consumers per stream. However, you can request a limit increase using the [Kinesis Data Streams limits form](https://docs.aws.amazon.com/support/v1?#/) . A given consumer can only be registered with one stream at a time.

For more information, see [Using Consumers with Enhanced Fan-Out](https://docs.aws.amazon.com/streams/latest/dev/introduction-to-enhanced-consumers.html) .

Enables or updates server-side encryption using an AWS KMS key for a specified stream.

> When invoking this API, you must use either the `StreamARN` or the `StreamName` parameter, or both. It is recommended that you use the `StreamARN` input parameter when you invoke this API.

Starting encryption is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns immediately and sets the status of the stream to `UPDATING` . After the update is complete, Kinesis Data Streams sets the status of the stream back to `ACTIVE` . Updating or applying encryption normally takes a few seconds to complete, but it can take minutes. You can continue to read and write data to your stream while its status is `UPDATING` . Once the status of the stream is `ACTIVE` , encryption begins for records written to the stream.

API Limits: You can successfully apply a new AWS KMS key for server-side encryption 25 times in a rolling 24-hour period.

Note: It can take up to 5 seconds after the stream is in an `ACTIVE` status before all records written to the stream are encrypted. After you enable encryption, you can verify that encryption is applied by inspecting the API response from `PutRecord` or `PutRecords` .

A Kinesis stream.

Can be encrypted with a KMS key.

Example: 

key := kms.NewKey(this, jsii.String("MyKey"))

kinesis.NewStream(this, jsii.String("MyEncryptedStream"), &StreamProps{
	Encryption: kinesis.StreamEncryption_KMS,
	EncryptionKey: key,
})

func NewStream 

func NewStream(scope constructs.Construct, id *string, props *StreamProps) Stream

type StreamAttributes 

type StreamAttributes struct {
	// The ARN of the stream.
	StreamArn *string `field:"required" json:"streamArn" yaml:"streamArn"`
	// The KMS key securing the contents of the stream if encryption is enabled.
	// Default: - No encryption.
	//
	EncryptionKey awskms.IKey `field:"optional" json:"encryptionKey" yaml:"encryptionKey"`
}

A reference to a stream.

The easiest way to instantiate is to call `stream.export()`. Then, the consumer can use `Stream.import(this, ref)` and get a `Stream`.

Example: 

importedStream := kinesis.Stream_FromStreamAttributes(this, jsii.String("ImportedEncryptedStream"), &StreamAttributes{
	StreamArn: jsii.String("arn:aws:kinesis:us-east-2:123456789012:stream/f3j09j2230j"),
	EncryptionKey: kms.Key_FromKeyArn(this, jsii.String("key"), jsii.String("arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012")),
})

type StreamEncryption 

type StreamEncryption string

What kind of server-side encryption to apply to this stream.

Example: 

key := kms.NewKey(this, jsii.String("MyKey"))

kinesis.NewStream(this, jsii.String("MyEncryptedStream"), &StreamProps{
	Encryption: kinesis.StreamEncryption_KMS,
	EncryptionKey: key,
})

const (
	// Records in the stream are not encrypted.
	StreamEncryption_UNENCRYPTED StreamEncryption = "UNENCRYPTED"
	// Server-side encryption with a KMS key managed by the user.
	//
	// If `encryptionKey` is specified, this key will be used, otherwise, one will be defined.
	StreamEncryption_KMS StreamEncryption = "KMS"
	// Server-side encryption with a master key managed by Amazon Kinesis.
	StreamEncryption_MANAGED StreamEncryption = "MANAGED"
)

type StreamMode added in v2.4.0 

type StreamMode string

Specifies the capacity mode to apply to this stream. 

const (
	// Specify the provisioned capacity mode.
	//
	// The stream will have `shardCount` shards unless
	// modified and will be billed according to the provisioned capacity.
	StreamMode_PROVISIONED StreamMode = "PROVISIONED"
	// Specify the on-demand capacity mode.
	//
	// The stream will autoscale and be billed according to the
	// volume of data ingested and retrieved.
	StreamMode_ON_DEMAND StreamMode = "ON_DEMAND"
)

type StreamProps 

type StreamProps struct {
	// The kind of server-side encryption to apply to this stream.
	//
	// If you choose KMS, you can specify a KMS key via `encryptionKey`. If
	// encryption key is not specified, a key will automatically be created.
	// Default: - StreamEncryption.KMS if encrypted Streams are supported in the region
	// or StreamEncryption.UNENCRYPTED otherwise.
	// StreamEncryption.KMS if an encryption key is supplied through the encryptionKey property
	//
	Encryption StreamEncryption `field:"optional" json:"encryption" yaml:"encryption"`
	// External KMS key to use for stream encryption.
	//
	// The 'encryption' property must be set to "Kms".
	// Default: - Kinesis Data Streams master key ('/alias/aws/kinesis').
	// If encryption is set to StreamEncryption.KMS and this property is undefined, a new KMS key
	// will be created and associated with this stream.
	//
	EncryptionKey awskms.IKey `field:"optional" json:"encryptionKey" yaml:"encryptionKey"`
	// The number of hours for the data records that are stored in shards to remain accessible.
	// Default: Duration.hours(24)
	//
	RetentionPeriod awscdk.Duration `field:"optional" json:"retentionPeriod" yaml:"retentionPeriod"`
	// The number of shards for the stream.
	//
	// Can only be provided if streamMode is Provisioned.
	// Default: 1.
	//
	ShardCount *float64 `field:"optional" json:"shardCount" yaml:"shardCount"`
	// The capacity mode of this stream.
	// Default: StreamMode.PROVISIONED
	//
	StreamMode StreamMode `field:"optional" json:"streamMode" yaml:"streamMode"`
	// Enforces a particular physical stream name.
	// Default: <generated>.
	//
	StreamName *string `field:"optional" json:"streamName" yaml:"streamName"`
}

Properties for a Kinesis Stream.

Example: 

key := kms.NewKey(this, jsii.String("MyKey"))

kinesis.NewStream(this, jsii.String("MyEncryptedStream"), &StreamProps{
	Encryption: kinesis.StreamEncryption_KMS,
	EncryptionKey: key,
