tCassandraOutputBulkExec Standard properties

These properties are used to configure tCassandraOutputBulkExec running in the Standard Job framework.

The Standard tCassandraOutputBulkExec component belongs to the Big Data and the Databases NoSQL families.

The component in this framework is available in all Talend products with Big Data and in Talend Data Fabric.

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.

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this option to view the schema only.

  • Change to built-in property: choose this option to change the schema to Built-in for local changes.

  • Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion.

    If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.


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.

When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually.

For more information, see Retrieving table schemas.

DB Version

Select the Cassandra version you are using.


Hostname or IP address of the Cassandra server.

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

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.

This field is only available when you select the Required authentication check box.


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.

Mapping type

Select the type of mapping from the drop-down list. If you select manual, you must enter the mapping in the Mapping field, for example "0=id, 1=name, 2=birthday".

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

Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it.

For more information about variables, see Using contexts and variables.


Usage rule

This component is mainly used when no particular transformation is required on the data to be loaded into the database.


Currently, the execution of this component ends the entire Job.
