Database Connection
Service URL
The URL of the CouchDB dataset to access.
Username and Password
Enter the username and password to access the database, user account, or wherever authentication is required.
Configuration
Number of Features to Read at a Time
Specifies how many features are read from the server at a time.
Setting a high value can result in increased performance, as there can be significant overhead associated with each network request.
Read Raw JSON
Specifies whether or not output features will have the couchdb_raw_json format attribute populated with the serialized representation of the JSON document.
If set to Yes, the couchdb_raw_json format attribute will automatically be exposed, and there will be no user attributes on the schema.
Constraints
Table List
After you have specified the database connection, click the Browse button to select tables for import. A connection window appears while the system compiles a table from the database.
Once the table list appears, you can select one or more tables, and then click OK to dismiss the window. The table name(s) will appear in the Table List field in the parameter box.
Schema Attributes
Additional Attributes to Expose
Use this parameter to expose Format Attributes in Workbench when you create a workspace:
- In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
- In a non-dynamic scenario where you have multiple feature types, it is convenient to expose additional attributes from one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.
