Data Lake Compute (DLC) supports configuring network (VPC) for data engine, facilitating management of engine access to different data source networks.

Network Configuration Type

According to different business scenarios, DLC provides two network configuration types.
Enhanced network configuration: suitable for accessing the data under one VPC with high speed and stability.
Note：
A data engine of a non-Spark job type can only be bound to one enhanced network configuration.
Cross-origin network configuration: suitable for cross-origin federated data query that needs to access multiple VPCs. A data engine can support binding multiple cross-origin network configurations.

Network Configuration Status

Initializing: The network configuration is being initialized. At this point, the network is not active.
Success: The network configuration takes effect on the bound engine.
Failure: The network configuration fails and can be deleted and reconfigured.

Network Configuration Security Policy

If you have configured a security group policy for the VPC, you need to add inbound rules for different network configuration types.
Enhanced network: Add inbound rules for the IP range of the VPC where the data source is located to the security group.
Cross-source network: Add inbound rules for the IP range of the engine bound to the network configuration to the security group.

Select the corresponding data catalog according to the source of the selected instance. The range of selectable data catalogs will be related to your account permission.
Data source VPC
No
The data engine network will connect all subnets in the VPC.
Bound data engine
Yes
Select the data engine associated with this network configuration. If the data engine is in isolated or initializing status, it will be unable to select.
Configuration Description
No
Not more than 100 characters.
4. Fill in, complete the settings and save. Then you can create a network configuration.
Note：
Once created, the network is in the initialization state. Subsequently, you can view the status in the list.

Delete Network Configuration

You can perform a deletion operation to manage the deletion of network configurations that are no longer needed or have failed to configure. Directions:
1. DLC console, choose service region.
2. Enter Engine Management > Engine Network Configuration through the left sidebar.
3. Find the network configuration that needs to be deleted. Support filtering search. Note the selection of network configuration type.
4. Click the Delete button. Just complete the deletion after secondary confirmation.
Note：
After deletion, this data engine will not be able to use this network configuration. If you need access, reconfiguration is required. Proceed with caution.

Modify Description Information

You can modify the description information of the configured network configuration by modifying the description information. Directions:
1. DLC console, choose service region.
2. Enter Engine Management > Engine Network Configuration through the left sidebar.
3. Find the network configuration that needs to be deleted. Support filtering search. Note the selection of network configuration type.
