25.1. URI Format
aws-kinesis-firehose://delivery-stream-name[?options]
The stream needs to be created prior to it being used.
You can append query options to the URI in the following format, ?options=value&option2=value&…
25.2. URI Options
The AWS Kinesis Firehose component supports 5 options which are listed below.

| accessKey (producer) | Amazon AWS Access Key | String | |
| secretKey (producer) | Amazon AWS Secret Key | String | |
| region (producer) | Amazon AWS Region | String | |
| resolveProperty Placeholders (advanced) | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | boolean |
The AWS Kinesis Firehose endpoint is configured using URI syntax:
aws-kinesis-firehose:streamName
with the following path and query parameters:
25.2.1. Path Parameters (1 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
| streamName | Required Name of the stream | String |
25.2.2. Query Parameters (7 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
| amazonKinesisFirehoseClient (producer) | Amazon Kinesis Firehose client to use for all requests for this endpoint | AmazonKinesisFirehose | |
| proxyHost (producer) | To define a proxy host when instantiating the DDBStreams client | String | |
| proxyPort (producer) | To define a proxy port when instantiating the DDBStreams client | Integer | |
| region (producer) | The region in which Kinesis client needs to work | String | |

Required Kinesis Firehose component options
You have to provide the amazonKinesisClient in the Registry with proxies and relevant credentials configured.
25.3. Usage
25.3.1. 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");25.3.2. 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(…).
25.3.3. Message headers set by the Kinesis producer on successful storage of a Record
| Header | Type | Description |
|---|---|---|
|
|
| The record ID, as defined in Response Syntax |
25.4. 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).
