aws ddb sink AWS DynamoDB Sink

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Send data to Amazon DynamoDB. The sent data inserts, updates, or deletes an item on the specified AWS DynamoDB table.

The basic authentication method for the AWS DynamoDB 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 client loads the credentials through this provider and doesn’t use the basic authentication method.

This Kamelet expects a JSON-formatted body and it must include the primary key values that define the DynamoDB item. The mapping between the JSON fields and table attribute values is done by key. For example, for '{"username":"oscerd", "city":"Rome"}' input, the Kamelet inserts or update an item in the specified AWS DynamoDB table and sets the values for the 'username' and 'city' attributes.

For PutItem operation the Json body defines all item attributes. For DeleteItem operation the Json body defines only the primary key attributes that identify the item to delete. For UpdateItem operation the Json body defines both key attributes to identify the item to be updated and all item attributes tht get updated on the item.

The given Json body can use "operation", "key" and "item" as top level properties that will be mapped to respective attribute value maps. { "operation": "PutItem" "key": {}, "item": {} }

Dependencies

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

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

  • camel:core

  • camel:jackson

  • 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:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:aws-ddb-sink"

You can now run it directly through the following command

camel run route.yaml
