Redis Connection Parameters

Table 1 Redis connection

Parameter

Mandatory

Description

Data Connection Type

Yes

Redis 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 (-).

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 the data migration job feature is 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 processing migration jobs only after apply for the trustlist membership. To use this feature, contact customer service or technical support.

Basic and Network Connectivity Configuration

Manual

No

This parameter is available when a proxy is used for connection. You can select Cluster Name Mode or Connection String Mode.

  • If you select Cluster Name Mode, select an existing cluster.
  • If you select Connection String Mode, enter the IP address and port of the corresponding cluster.

MRS Cluster Name

Yes
The name of the MRS cluster. Select an MRS cluster that Hive belongs to. Only MRS clusters are supported. A Hadoop cluster can be selected only after it is managed by MRS. All the MRS clusters with the same project ID and enterprise project are displayed.
NOTE:

DataArts Studio does not support MRS clusters whose Kerberos encryption type is aes256-sha2,aes128-sha2, and only supports MRS clusters whose Kerberos encryption type is aes256-sha1,aes128-sha1.

If the connection fails after you select a cluster, check whether the MRS cluster can communicate with the CDM instance which functions as the agent. They can communicate with each other in the following scenarios:
  • If the CDM cluster in the DataArts Studio instance and the MRS cluster are in different regions, a public network or a dedicated connection is required. If the Internet is used for communication, ensure that an EIP has been bound to the CDM cluster, and the MRS cluster can access the Internet and the port has been enabled in the firewall rule.
  • If the CDM cluster in the DataArts Studio instance and the MRS cluster are in the same region, VPC, subnet, and security group, they can communicate with each other by default. If they are in the same VPC but in different subnets or security groups, you must configure routing rules and security group rules. For details about how to configure routing rules, see Configuring Routing Rules. For details about how to configure security group rules, see Configuring Security Group Rules.
  • The MRS cluster and the DataArts Studio workspace belong to the same enterprise project. If they do not, you can modify the enterprise project of the workspace.
NOTE:

If an agent is connected to multiple MRS clusters and one of the MRS clusters is deleted or abnormal, connections to the other MRS clusters will be affected. Therefore, you are advised to connect an agent to only one MRS cluster.

Server List

Yes

This parameter is displayed when Manual is set to Connection String Mode.

One or more servers (server domain name/IP address:server port) separated by commas (,)

Example: 192.168.0.1:27017 or 192.168.0.2:27017

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

The CDM cluster provides an agent for communications between DataArts Studio and GBase. When creating a GBase connection, select a CDM cluster. If no CDM cluster is available, create one first.

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

Authentication Method

Yes

This parameter is mandatory when Manual is set to Connection String Mode.

Select the authentication type of the database.

The options include SIMPLE and KERBEROS.

Password

Yes

Password for accessing the database. The password is required for creating a cluster.
