*Available as of Camel version 2.19*

The Kinesis Firehose component supports sending messages to Amazon Kinesis Firehose service.

Prerequisites

You must have a valid Amazon Web Services developer account, and be
signed up to use Amazon Kinesis Firehose. More information are available
at https://aws.amazon.com/kinesis/firehose/[AWS Kinesis Firehose]

### URI Format

[source,java]
-----------------------------------
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&...

### URI Options

Required Kinesis Firehose component options

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


### Usage

#### Amazon Kinesis Firehose configuration

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

[source,java]
--------------------------------------------------------------------------------------------------------------------
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.

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

#### Providing AWS Credentials

It is recommended that the credentials are obtained by using the
http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/DefaultAWSCredentialsProviderChain.html[DefaultAWSCredentialsProviderChain]
that is the default when creating a new ClientConfiguration instance,
however, a
different http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/AWSCredentialsProvider.html[AWSCredentialsProvider]
can be specified when calling createClient(...).

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

[width="100%",cols="10%,10%,80%",options="header",]
|=======================================================================
|Header |Type |Description

|`CamelAwsKinesisFirehoseRecordId` |`String` |The record ID, as defined in
http://docs.aws.amazon.com/firehose/latest/APIReference/API_PutRecord.html#API_PutRecord_ResponseSyntax[Response Syntax]


|=======================================================================

### Dependencies

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

*pom.xml*

[source,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).
