tMongoDBConfiguration properties for Apache Spark Streaming

Property type

Either Built-In or Repository.

Built-In: No property data stored centrally.

Repository: Select the repository file where the properties are stored.

DB Version

Select the version of the MongoDB database you need to connect to.

Use connection string

Then you need to click the [...] button and enter the URI in double quotation marks in the Enter a new password pop-up dialog box that appears, and finally click OK to save the settings.

Note that the URI directly provide the username and password so the Username and Password parameters are not available.

For more information, see Connection String URI Format from MongoDB documentation.

This option is only available when you select MongoDB 4+ from the DB Version drop-down list and when you have installed the 8.0.1-R2023-05 Talend Studio Monthly update or a later one delivered by Talend.

Use replica set address or multiple query routers

Select this check box to show the Server addresses table.

In the Server addresses table, define the shared MongoDB databases or the MongoDB replica sets you want to connect to.

Server and Port

Enter the IP address and listening port of the database server.

Available when the Use replica set address or multiple query routers check box is not selected.

Database

Enter the name of the MongoDB database to be connected to.

Use SSL connection

Select this check box to enable the SSL or TLS encrypted connection.

Then you need to use the tSetKeystore component in the same Job to specify the encryption information.

"spark.executor.extraJavaOptions" :
"-Djavax.net.ssl.trustStorePassword
=password 
-Djavax.net.ssl.trustStore=
/tmp/keystore.jks 
-Djavax.net.ssl.trustStoreType=JKS"

Note that the SSL connection is available only for the version 2.4 + of MongoDB.

Use authentication

If the MongoDB database to be used requires authentication, select this check box to enable the database authentication.

Among the mechanisms listed on the Authentication mechanism drop-down list, the NEGOTIATE one is recommended if you are not using Kerberos, because it automatically select the authentication mechanism the most adapted to the MongoDB version you are using.

For details about the other mechanisms in this list, see MongoDB Authentication from the MongoDB documentation.

Set Authentication database

If the username to be used to connect to MongoDB has been created in a specific Authentication database of MongoDB, select this check box to enter the name of this Authentication database in the Authentication database field that is displayed.

For further information about the MongoDB Authentication database, see User Authentication database.

Username and Password

Enter the DB user authentication data.

To enter the password, click the [...] button next to the password field, enter the password in double quotes in the pop-up dialog box, and click OK to save the settings.

These options are available when the Use authentication check box is selected and when the Use connection string check box is cleared.

If the security system you have selected from the Authentication mechanism drop-down list is Kerberos, you need to enter the User principal, the Realm and the KDC server fields instead of the Username and the Password fields.

Connection string options

You can define more properties in this table for the connection to MongoDB, in addition to the properties defined in the Basic settings tab.

connectTimeoutMS=300000

For further information about the options you can add in this table, see Connection options.

Usage rule

This component is used with no need to be connected to other components.

The configuration in a tMongoDBConfiguration component applies only on the MongoDB related components in the same Job. In other words, the MongoDB components used in a child or a parent Job that is called via tRunJob cannot reuse this configuration.

This component, along with the Spark Streaming component Palette it belongs to, appears only when you are creating a Spark Streaming Job.

Note that in this documentation, unless otherwise explicitly stated, a scenario presents only Standard Jobs, that is to say traditional Talend data integration Jobs.

Spark Connection

This connection is effective on a per-Job basis.
