scope^Required

• Type: ros_cdk_core.Construct

id^Required

• Type: str

file_system_id^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property fileSystemId: File system ID.

fset_id^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property fsetId: Fileset ID.

source_storage^Required

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property sourceStorage: Access path stored at the source.Format: : \/\/ . in: Storage Type: Currently only supports OSS. PATH: OSS's bucket name.Limit the following. Only support the lowercase letters, numbers and short strokes (-) and must start with a lowercase letter or number. The length is 8 ~ 128 English characters. Use UTF-8 encoding. Can't start with http: \/\/ and https: \/\/. Explain that the OSS BUCKET must be the bucket that exists in the region.

throughput^Required

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

Property throughput: The upper limit of transmission bandwidth for data flow, unit: MB\/s. Value: 600 1200 1500.

Explanation The transmission bandwidth of the data flow must be smaller than the IO bandwidth of the file system.

auto_refresh_interval^Optional

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

Property autoRefreshInterval: The automatic update interval time, every time the interval, the CPFS checks whether there is a data update in the directory.

If there is data update, start the automatic update task, unit: minute. Scope of value: 5 ~ 525600, default value: 10.

auto_refresh_policy^Optional

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property autoRefreshPolicy: Automatic update strategy, after the source data is updated, the data update is introduced to the CPFS strategy.

None (default): The data update of the source is not automatically imported into CPFS. Users can import data update at the source end of the source through data flow tasks. Importchanged: The data update at the source automatically imports CPFS.

auto_refreshs^Optional

• Type: typing.Union[ros_cdk_core.IResolvable, typing.List[typing.Union[ros_cdk_core.IResolvable, AutoRefreshsProperty]]]

Property autoRefreshs:.

description^Optional

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property description: Description of data flow.

limit: The length is 2 to 128 English or Chinese characters. Start with a lowercase letter or Chinese, and you cannot start with http:// and https: //. It can contain numbers, half-horn colon (:), down line (_) or short lines (-).

source_security_type^Optional

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property sourceSecurityType: The type of safety protection types of the source storage.

If the source storage must be protected through safety protection, please specify the type of safety protection type storage.Value: No (default value): It means that the source storage does not need to be accessed by safe protection. SSL: Protective access through SSL certificates.

enable_resource_property_constraint^Optional

• Type: bool

Methods

to_string

def to_string() -> str

Returns a string representation of this construct.

synthesize

def synthesize(
  session: ISynthesisSession
) -> None

Allows this construct to emit artifacts into the cloud assembly during synthesis.

This method is usually implemented by framework-level constructs such as Stack and Asset as they participate in synthesizing the cloud assembly.

session^Required

• Type: ros_cdk_core.ISynthesisSession

The synthesis session.

add_condition

def add_condition(
  condition: RosCondition
) -> None

condition^Required

• Type: ros_cdk_core.RosCondition

add_count

def add_count(
  count: typing.Union[typing.Union[int, float], IResolvable]
) -> None

count^Required

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

add_dependency

def add_dependency(
  resource: Resource
) -> None

resource^Required

• Type: ros_cdk_core.Resource

add_resource_desc

def add_resource_desc(
  desc: str
) -> None

desc^Required

• Type: str

apply_removal_policy

def apply_removal_policy(
  policy: RemovalPolicy
) -> None

policy^Required

• Type: ros_cdk_core.RemovalPolicy

fetch_condition

def fetch_condition() -> RosCondition

fetch_dependency

def fetch_dependency() -> typing.List[str]

fetch_resource_desc

def fetch_resource_desc() -> str

get_att

def get_att(
  name: str
) -> IResolvable

name^Required

• Type: str

set_metadata

def set_metadata(
  key: str,
  value: typing.Any
) -> None

key^Required

• Type: str

value^Required

• Type: typing.Any

Static Functions

is_construct

import ros_cdk_nas
ros_cdk_nas.DataFlow.is_construct(
  x: typing.Any
)

Return whether the given object is a Construct.

x^Required

• Type: typing.Any

Properties

node: ConstructNode

• Type: ros_cdk_core.ConstructNode

The construct tree node associated with this construct.

env^Required

env: IResourceEnvironment

• Type: ros_cdk_core.IResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.
