Stream

class aws_cdk.aws_kinesis.Stream(scope, id, *, encryption=None, encryption_key=None, retention_period=None, shard_count=None, stream_mode=None, stream_name=None)

Bases: Resource

A Kinesis stream.

Can be encrypted with a KMS key.

ExampleMetadata:: infused

Example:

key = kms.Key(self, "MyKey")

kinesis.Stream(self, "MyEncryptedStream",
    encryption=kinesis.StreamEncryption.KMS,
    encryption_key=key
)

Parameters:

scope (Construct) –
id (str) –
encryption (Optional[StreamEncryption]) – 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_key (Optional[IKey]) – 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.
retention_period (Optional[Duration]) – The number of hours for the data records that are stored in shards to remain accessible. Default: Duration.hours(24)
shard_count (Union[int, float, None]) – The number of shards for the stream. Can only be provided if streamMode is Provisioned. Default: 1
stream_mode (Optional[StreamMode]) – The capacity mode of this stream. Default: StreamMode.PROVISIONED
stream_name (Optional[str]) – Enforces a particular physical stream name. Default:

Methods

apply_removal_policy(policy)

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (RemovalPolicy) –

Return type:

None

grant(grantee, *actions)

Grant the indicated permissions on this stream to the given IAM principal (Role/Group/User).

Parameters:

grantee (IGrantable) –
actions (str) –

Return type:

Grant

grant_read(grantee)

Grant read permissions for this stream and its contents to an IAM principal (Role/Group/User).

If an encryption key is used, permission to ues the key to decrypt the contents of the stream will also be granted.

Parameters:

grantee (IGrantable) –

Return type:

Grant

grant_read_write(grantee)

Grants read/write permissions for this stream and its contents to an IAM principal (Role/Group/User).

If an encryption key is used, permission to use the key for encrypt/decrypt will also be granted.

Parameters:

grantee (IGrantable) –

Return type:

Grant

grant_write(grantee)

Grant write permissions for this stream and its contents to an IAM principal (Role/Group/User).

If an encryption key is used, permission to ues the key to encrypt the contents of the stream will also be granted.

Parameters:

grantee (IGrantable) –

Return type:

Grant

metric(metric_name, *, account=None, color=None, dimensions=None, dimensions_map=None, label=None, period=None, region=None, statistic=None, unit=None)

Return stream metric based from its metric name.

Parameters:

metric_name (str) – name of the stream metric.
account (Optional[str]) – Account which this metric comes from. Default: - Deployment account.
color (Optional[str]) – The hex color code, prefixed with ‘#’ (e.g. ‘#00ff00’), to use when this metric is rendered on a graph. The Color class has a set of standard colors that can be used here. Default: - Automatic color
dimensions (Optional[Mapping[str, Any]]) – (deprecated) Dimensions of the metric. Default: - No dimensions.
dimensions_map (Optional[Mapping[str, str]]) – Dimensions of the metric. Default: - No dimensions.
label (Optional[str]) – Label for this metric when added to a Graph in a Dashboard. You can use dynamic labels to show summary information about the entire displayed time series in the legend. For example, if you use:: [max: ${MAX}] MyMetric As the metric label, the maximum value in the visible range will be shown next to the time series name in the graph’s legend. Default: - No label
period (Optional[Duration]) – The period over which the specified statistic is applied. Default: Duration.minutes(5)
region (Optional[str]) – Region which this metric comes from. Default: - Deployment region.
statistic (Optional[str]) – What function to use for aggregating. Can be one of the following: - “Minimum” | “min” - “Maximum” | “max” - “Average” | “avg” - “Sum” | “sum” - “SampleCount | “n” - “pNN.NN” Default: Average
unit (Optional[Unit]) – Unit used to filter the metric stream. Only refer to datums emitted to the metric stream with the given unit and ignore all others. Only useful when datums are being emitted to the same metric stream under different units. The default is to use all matric datums in the stream, regardless of unit, which is recommended in nearly all cases. CloudWatch does not honor this property for graphs. Default: - All metric datums in the given metric stream
