aws ddb streams source AWS DynamoDB Streams Source

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Receive events from Amazon DynamoDB Streams.

The basic authentication method for the AWS DynamoDB Streams service is to specify an access key and a secret key. These parameters are optional because the Kamelet provides a default credentials provider.

If you use the default credentials provider, the DynamoDB Streams client loads the credentials through this provider and doesn’t use the basic authentication method.

Dependencies

At runtime, the aws-ddb-streams-source Kamelet relies upon the presence of the following dependencies:

  • mvn:org.apache.camel.kamelets:camel-kamelets-utils:4.8.0-SNAPSHOT

  • camel:gson

  • camel:aws2-ddb

  • camel:kamelet

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:aws-ddb-streams-source"
      parameters:
        .
        .
        .
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml
