Use location hosting to manage data in the data lake OSS to DLF - Data Lake Formation

Location hosting allows you to manage and analyze the stored data in the data lake Object Storage Service (OSS) by hosting it to Data Lake Formation (DLF). After hosting the location, it will provide you with Storage overview, Lifecycle management, and Data overview of data tables (such as data access frequency, last data update time), and data lake management capabilities such as storage permissions.

Procedure

Register a location

Log on to the Data Lake Formation console.
In the left-side navigation pane, click Lake Management > Location Hosting.
Click Register Location.
On the Register Location page, configure the following parameters and click OK.
- Select OSS Path: Select the OSS bucket to be registered (multiple selections allowed).
- RAM Role: Select RAM authorization role, default is AliyunDLFWorkFlowDefaultRole.
- Enable OSS Bucket Inventory, Enable OSS Logging: Enabled by default. If you have already activated this feature in the OSS console, it will not be activated again. The default setting is to clean data every 7 days to save your storage costs.
  Important
  Bucket inventory and Logging will incur additional Storage fees. The following are example fees for actual tests for your reference:
  - Example of bucket inventory fees: 100 million files (7-day automatic cleanup), approximately 0.37 RMB/month.
  - Example of log storage fees: Assuming 400 million API calls per month (7-day automatic cleanup), approximately 5 RMB/month.
