Hello,

Do you want to use it in DI job or bigdata spark job?

For Apache Spark job, here is a TalendHelpCenter:tCassandraConfiguration component. You can define the Cassandra consistency level for reading in configuration field.

Hello,

So far, tCassandraConfiguration component in this framework is available only if you have subscribed to one of the Talend solutions with Big Data not open source.
