Basic settings

Property Type	Select the way the connection details will be set. Built-In: The connection details will be set locally for this component. You need to specify the values for all related connection properties manually. Repository: The connection details stored centrally in Repository > Metadata will be reused by this component.

Use an existing connection	Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.
Schema and Edit Schema	A schema is a row description, and it defines the fields to be processed and passed on to the next component. Built-In: You create and store the schema locally for this component only. Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. Click Edit schema to make changes to the schema. If you make changes, the schema automatically becomes built-in. Click Guess schema to retrieve the table schema.
Host and Port	Enter the IP address and listening port of the database server.
Database	Enter the name of the Amazon DocumentDB database.
Need auth	Select this check box to enable the database authentication. Among the mechanisms listed on the Auth mechanism drop-down list, select either Negotiate, which is recommended because it automatically select the most adapted authentication mechanism, or SCRAM-SHA-1 SASL, or SCRAM-SHA-256. Select the Use auth database check box to enter the name of the authentication database in which the username to be used to connect to Amazon DocumentDB has been created and enter the database user authentication data in the Username and Password fields. To enter the password, click the [...] button next to the Password field to bring out the Enter a new password dialog box, enter the password in the text field, and click OK. Note that you can enter the password either in a JSON string in the pure password mode or as a Java expression in the Java mode. You can toggle between the two modes by clicking switch to Java mode or switch to pure password mode on the top of the text field. Information noteNote: The two password modes are available only when you have installed the 8.0.1-R2022-05 Talend Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator. If the 8.0.1-R2022-05 Talend Studio Monthly update or a later one delivered by Talend is not installed, you can enter passwords in the Java mode only.
Use SSL connection	Select this check box to enable the SSL or TLS encrypted connection. Then you must specify the encryption information using one of these methods: If you want to centralize the connection information, set up the SSL connection in Windows > Preferences > Talend > SSL and check the Enable SSL field in the MongoDB connection configuration in Metadata. If you want to keep this information within the scope of this Job, use the tSetKeystore component in the same Job.
