Basic settings

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 Cassandra version you are using.Cassandra 2.0.0 only works with JVM1.7.


Hostname or IP address of the Cassandra server.


Listening port number of the Cassandra server.

Required authentication

Select this check box to provide credentials for the Cassandra authentication.


Fill in this field with the username for the Cassandra authentication.


Fill in this field with the password for the Cassandra authentication.

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

Use configuration file

Select this check box and in the field that is displayed, enter the path, or browse to cassandra.yaml, the main configuration file for Cassandra.

This way, this component can import and directly use the configuration from cassandra.yaml, which can contain many advanced Cassandra properties, such as the properties for SSL encryption.

When you need to run your Job in different Cassandra environments, this feature allows your Job to easily switch between the configurations.

For further information about this cassandra.yaml file, see Cassandra configuration.


Type in the name of the keyspace into which you want to write the SSTable.

Column family

Type in the name of the column family into which you want to write the SSTable.

SSTable directory

Specify the local directory of the SSTable to be loaded into Cassandra. Note that the complete path to the SSTable will be the local directory appended by the specified keyspace name and column family name.

For example, if you set the local directory to /home/talend/sstable, and specify testk as the keyspace name and testc as the column family name, the complete path to the SSTable will be /home/talend/sstable/testk/testc/.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level as well as at each component level.

Global Variables
