DWS Connection Parameters
Parameter |
Mandatory |
Description |
---|---|---|
Data Connection Type |
Yes |
DWS is selected 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 (-). |
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:
|
Basic and Network Connectivity Configuration |
||
SSL Encryption |
Yes |
DWS supports SSL encryption and certificate authentication for communication between the client and server. You can set this parameter based on whether SSL connection is mandatory on the server.
|
Manual |
Yes |
Select either of the following modes:
|
DWS Cluster Name |
Yes |
This parameter is mandatory when Manual is set to Cluster Name Mode. Select a DWS cluster from all the DWS clusters with the same project ID and enterprise project. |
IP Address or Domain Name |
Yes |
This parameter is mandatory when Manual is set to Connection String Mode. If you choose to manually enter an IP address or domain name, you must enter an internal IP address and a port that is accessible to the network segment of the resource group. Otherwise, the network is disconnected.
This parameter indicates the address for accessing the cluster database through an internal network. Enter an IP address or domain name. The IP address or domain name is automatically generated during cluster creation. You can obtain them on the management console by performing the following operations:
|
Port |
Yes |
This parameter is mandatory when Manual is set to Connection String Mode. This parameter indicates the database port number specified during the DWS cluster creation. Ensure that you have enabled this port in the security group rule so that the DataArts Studio instance can connect to the database in the DWS cluster through this port. |
KMS Key |
Yes |
KMS key used to encrypt and decrypt data source authentication information. Select a default or custom key.
NOTE:
When you use KMS for encryption through DataArts Studio or KPS for the first time, the default key dlf/default or kps/default is automatically generated. For more information about default keys, see What Is a Default Master Key?. |
Agent |
Yes |
Data Warehouse Service (DWS) is not a fully managed service and thus cannot be directly connected to DataArts Studio. A CDM cluster can provide an agent for DataArts Studio to communicate with non-fully-managed services. Therefore, you need to select a CDM cluster when creating a DWS data connection. If no CDM cluster is available, create one first. As a network proxy, the CDM cluster must be able to communicate with the DWS cluster. To ensure network connectivity, the CDM cluster must be in the same region and AZ and use the same VPC and subnet as the DWS cluster. The security group rule must also allow the CDM cluster communicate with the DWS cluster.
NOTE:
If a CDM cluster functions as the agent for a data connection in Management Center, the cluster supports a maximum of 200 concurrent active threads. If multiple data connections share an agent, a maximum of 200 SQL, Shell, and Python scripts submitted through the connections can run concurrently. Excess tasks will be queued. You are advised to plan multiple agents based on the workload. |
Data Source Authentication and Other Function Configuration |
||
Username |
Yes |
The database username, which is specified when the DWS cluster is created. |
Password |
Yes |
The password for accessing the database, which is specified when the DWS cluster is created. |
