Description

By creating a CloudTable link, you can extract data from or load data to CloudTable.

Sample Link

The following is the message body of a sample link. You are advised to store the AK and SK in ciphertext in the configuration file or environment variables and decrypt them when needed to ensure security.

Link Parameters

Parameter	Mandatory	Type	Description
linkConfig.hbaseType	Yes	Enumeration	HBase type. The options are as follows: CloudTable: link to CloudTable MRS: link to MRS FusionInsight HD: link to FusionInsight HD Apache Hadoop: link to Apache Hadoop
linkConfig.zookeeperQuorum	Yes	String	ZooKeeper link of CloudTable. This parameter is mandatory for the CloudTable link.
linkConfig.iamAuth	Yes	Boolean	If you choose IAM for identity authentication, enter the username, AK, and SK.
linkConfig.runMode	Yes	Enumeration	Running mode of the HBase link. The options are as follows: EMBEDDED: The link instance runs with CDM. This mode delivers better performance. STANDALONE: The link instance runs in an independent process. If CDM needs to connect to multiple Hadoop data sources (MRS, Hadoop, or CloudTable) with both Kerberos and Simple authentication methods, STANDALONE is used.
linkConfig.cloudtableUser	Yes	String	Username for accessing the CloudTable cluster
linkConfig.accessKey	Yes	String	AK for accessing the CloudTable cluster. You are advised to store it in ciphertext in the configuration file or an environment variable and decrypt it when needed to ensure security.
linkConfig.securityKey	Yes	String	SK for accessing the CloudTable cluster. You are advised to store it in ciphertext in the configuration file or an environment variable and decrypt it when needed to ensure security.
