Dependencies

At runtime, the cassandra-source Kamelet relies upon the presence of the following dependencies:

camel:jackson
camel:kamelet
camel:cassandraql

Camel JBang usage

Prerequisites

You’ve installed JBang.
You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:cassandra-source"
      parameters:
        .
        .
        .
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml
