DLI Connection Parameters

Table 1 DLI connection

Parameter

Mandatory

Description

Data Connection Type

Yes

DLI is selected by default and cannot be changed.

Name

Yes

Name of the data connection to create. Data connection names can contain a maximum of 100 characters. They can contain only letters, digits, underscores (_), and hyphens (-).

Description

No

A description which can help identify the data connection more easily. It can contain a maximum of 100 characters.

Tag

No

Attribute of the data connection to create. Tags make management easier.
NOTE:

The tag name can contain only letters, digits, and underscores (_) and cannot start with an underscore (_) or contain more than 100 characters.

Applicable Modules

Yes

Select the modules for which this connection is available.

NOTE:
  • When offline or real-time data migration jobs are enabled, you can select the DataArts Migration module. Then you can select this data connection when creating a data migration job in DataArts Factory.
  • You can use offline or real-time data migration jobs only after you apply for the whitelist membership. To use this feature, contact customer service or technical support.

Data Source Authentication and Other Function Configuration

Real-time Metadata Synchronization

Yes

When real-time metadata synchronization is enabled, the metadata of DLI is synchronized to the Data Map component in real time. You are advised to enable this function.

NOTE:

Whether real-time metadata synchronization is enabled depends on whether this function is enabled for the latest DLI connection in the DataArts Studio instance. That is, if real-time synchronization is disabled or enabled for a DLI connection, this function is also disabled or enabled for all DLI connections.

For example, if there is a DLI connection in a workspace of a DataArts Studio instance and another DLI connection in another workspace, and real-time metadata synchronization is enabled for the connection that is created first and disabled for the connection that is created later, then real-time metadata synchronization is disabled for DLI. If real-time metadata synchronization is disabled for the connection that is created first and enabled for the connection that is created later, then real-time metadata synchronization is enabled for DLI.

Metadata Collection Scope

No

Databases and data tables whose metadata will be synchronized in real time. If this parameter is not set, all metadata will be synchronized.

The value can be in either of the following formats:

  • database_name: databases whose names contain database_name
  • database_name.table_name: databases whose names contain database_name and data tables whose names contain table_name

Examples:

  • If you enter datatest, the metadata of the tables in the databases whose names contain datatest will be synchronized in real time.
  • If you enter datatest.table1, metadata of the tables whose names contain table_name in the databases whose names contain datatest will be synchronized in real time.

Basic and Network Connectivity Configuration

Project ID

No

This parameter is displayed when DataArts Migration is selected for Applicable Modules.

Project ID in the region where DLI resides

A project is a group of tenant resources, and an account ID corresponds to the current account. The IAM ID corresponds to the current user. You can view the project IDs, account IDs, and user IDs in different regions on the corresponding pages.
  1. Register with and log in to the management console.
  2. Hover the cursor on the username in the upper right corner and select My Credentials from the drop-down list.
  3. On the API Credentials page, obtain the account name, account ID, IAM username, and IAM user ID, and obtain the project and its ID from the project list.
