        encryption_type="encryptionType",
        key_id="keyId"
    ),
    stream_mode_details=kinesis.CfnStream.StreamModeDetailsProperty(
        stream_mode="streamMode"
    ),
    tags=[CfnTag(
        key="key",
        value="value"
    )]
)

Create a new AWS::Kinesis::Stream.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
name (Optional[str]) – The name of the Kinesis stream. If you don’t specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the stream name. For more information, see Name Type . If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.
retention_period_hours (Union[int, float, None]) – The number of hours for the data records that are stored in shards to remain accessible. The default value is 24. For more information about the stream retention period, see Changing the Data Retention Period in the Amazon Kinesis Developer Guide.
shard_count (Union[int, float, None]) – The number of shards that the stream uses. For greater provisioned throughput, increase the number of shards.
stream_encryption (Union[StreamEncryptionProperty, Dict[str, Any], IResolvable, None]) – When specified, enables or updates server-side encryption using an AWS KMS key for a specified stream. Removing this property from your stack template and updating your stack disables encryption.
stream_mode_details (Union[IResolvable, StreamModeDetailsProperty, Dict[str, Any], None]) – Specifies the capacity mode to which you want to set your data stream. Currently, in Kinesis Data Streams, you can choose between an on-demand capacity mode and a provisioned capacity mode for your data streams.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – An arbitrary set of tags (key–value pairs) to associate with the Kinesis stream. For information about constraints for this property, see Tag Restrictions in the Amazon Kinesis Developer Guide .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:: target (CfnResource)
Return type:: None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str)
value (Any)

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

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 (Optional[RemovalPolicy])
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:: key (str)
See:
Return type:: Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters:

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Return type:

None

override_logical_id(new_logical_id)

Overrides the auto-generated logical ID with a specific ID.

Parameters:: new_logical_id (str) – The new logical ID to use for this stack element.
Return type:: None

to_string()

Returns a string representation of this construct.

Return type:: str
Returns:: a string representation of this resource

Attributes

CFN_RESOURCE_TYPE_NAME = 'AWS::Kinesis::Stream'

attr_arn

The Amazon resource name (ARN) of the Kinesis stream, such as arn:aws:kinesis:us-east-2:123456789012:stream/mystream .

CloudformationAttribute:: Arn

cfn_options: Options for this resource, such as condition, update policy etc.

the stack trace of the point where this Resource was created from, sourced from the +metadata+ entry typed +aws:cdk:logicalId+, and with the bottom-most node +internal+ entries filtered.

logical_id

The logical ID for this CloudFormation stack element.

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

name

The name of the Kinesis stream.

If you don’t specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the stream name. For more information, see Name Type .

If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-kinesis-stream.html#cfn-kinesis-stream-name

node: The construct tree node associated with this construct.

ref

Return a string that will be resolved to a CloudFormation { Ref } for this element.

If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through Lazy.any({ produce: resource.ref }).

retention_period_hours

The number of hours for the data records that are stored in shards to remain accessible.

The default value is 24. For more information about the stream retention period, see Changing the Data Retention Period in the Amazon Kinesis Developer Guide.

Removing this property from your stack template and updating your stack disables encryption.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-kinesis-stream.html#cfn-kinesis-stream-streamencryption

stream_mode_details

Specifies the capacity mode to which you want to set your data stream.

Currently, in Kinesis Data Streams, you can choose between an on-demand capacity mode and a provisioned capacity mode for your data streams.

StreamEncryptionProperty

class CfnStream.StreamEncryptionProperty(*, encryption_type, key_id)

Bases: object

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 .

Parameters:

encryption_type (str) – The encryption type to use. The only valid value is KMS .
key_id (str) – The GUID for the customer-managed AWS KMS key to use for encryption. This value can be a globally unique identifier, a fully specified Amazon Resource Name (ARN) to either an alias or a key, or an alias name prefixed by “alias/”.You can also use a master key owned by Kinesis Data Streams by specifying the alias aws/kinesis . - Key ARN example: arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012 - Alias ARN example: arn:aws:kms:us-east-1:123456789012:alias/MyAliasName - Globally unique key ID example: 12345678-1234-1234-1234-123456789012 - Alias name example: alias/MyAliasName - Master key owned by Kinesis Data Streams: alias/aws/kinesis
