DataFlow

This class encapsulates and extends the ROS resource type ALIYUN::NAS::DataFlow, which is used to create a data flow between a Cloud Parallel File Storage (CPFS) file system and an Object Storage Service (OSS) bucket.

  • Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property fileSystemId: File system ID.

fsetIdRequired

  • Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property fsetId: Fileset ID.

sourceStorageRequired

  • Type: java.lang.String OR com.aliyun.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.

throughputRequired

  • Type: java.lang.Number OR com.aliyun.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.

autoRefreshIntervalOptional

  • Type: java.lang.Number OR com.aliyun.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.

autoRefreshPolicyOptional

  • Type: java.lang.String OR com.aliyun.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.

autoRefreshsOptional

  • Type: com.aliyun.ros.cdk.core.IResolvable OR java.util.ListAutoRefreshsProperty>

Property autoRefreshs:.

descriptionOptional

  • Type: java.lang.String OR com.aliyun.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 (-).

sourceSecurityTypeOptional

  • Type: java.lang.String OR com.aliyun.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.
