Elasticsearch Connection Parameters (Internal Test)

**Table 1** Elasticsearch connection
Parameter	Mandatory	Description
Data Connection Type	Yes	Elasticsearch 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. The connection can be used in the selected modules. 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.
Basic and Network Connectivity Configuration
Elasticsearch Server List	Yes	One or more server lists (server domain name/IP address:server port) separated by semicolons (;). Example: 192.168.0.1:9200;192.168.0.2:9200
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?. Only symmetric keys are supported. Asymmetric keys are not supported.
Agent	Yes	DataArts Studio cannot directly connect to non-fully managed services. An agent is required for DataArts Studio to communicate with non-fully managed services. A CDM cluster can function as an agent. If no CDM cluster is available, create one by referring to Creating a CDM Cluster.
Data Migration Configuration
Security Mode Authentication	Yes	Whether to enable security mode authentication.
HTTPS Access	Yes	Whether to enable HTTPS access. Accessing a cluster through HTTPS improves security but deteriorates cluster performance.
Connection timeout	No	Connection timeout duration, in milliseconds. The default value is 10000.
Socket timeout	No	Timeout duration, in milliseconds. The default value is 60000.
Enable GZIP compression	No	Whether to enable GZIP compression. Set http.compression to true on the Elasticsearch node.
Data Source Authentication and Other Function Configuration
Username	Yes	Username for connecting to Elasticsearch
Password	Yes	Password for connecting to Elasticsearch
