Required Kinesis Firehose component options

You have to provide the amazonKinesisClient in the Registry with proxies and relevant credentials configured.

28.4. Usage

28.4.1. Amazon Kinesis Firehose configuration

You will need to create an instance of AmazonKinesisClient and bind it to the registry

ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

Region region = Region.getRegion(Regions.fromName(region));
region.createClient(AmazonKinesisClient.class, null, clientConfiguration);
// the 'null' here is the AWSCredentialsProvider which defaults to an instance of DefaultAWSCredentialsProviderChain

registry.bind("kinesisFirehoseClient", client);

You then have to reference the AmazonKinesisFirehoseClient in the amazonKinesisFirehoseClient URI option.

from("aws-kinesis-firehose://mykinesisdeliverystream?amazonKinesisFirehoseClient=#kinesisClient")
  .to("log:out?showAll=true");

28.4.2. Providing AWS Credentials

It is recommended that the credentials are obtained by using the DefaultAWSCredentialsProviderChain that is the default when creating a new ClientConfiguration instance, however, a different AWSCredentialsProvider can be specified when calling createClient(…​).

28.4.3. Message headers set by the Kinesis producer on successful storage of a Record

HeaderTypeDescription

CamelAwsKinesisFirehoseRecordId

String

The record ID, as defined in Response Syntax

28.5. Dependencies

Maven users will need to add the following dependency to their pom.xml.

pom.xml

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-aws</artifactId>
    <version>${camel-version}</version>
</dependency>

where ${camel-version} must be replaced by the actual version of Camel (2.19 or higher).
