AWS Kinesis Firehose Component

Since Camel 2.19

Only producer is supported

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 AWS Kinesis Firehose

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&…​

URI Options

The AWS Kinesis Firehose component supports 7 options, which are listed below.

Name Description Default Type

configuration (advanced)

The AWS Kinesis Firehose default configuration

KinesisFirehoseConfiguration

accessKey (producer)

Amazon AWS Access Key

String

secretKey (producer)

Amazon AWS Secret Key

String

region (producer)

Amazon AWS Region

String

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

The AWS Kinesis Firehose endpoint is configured using URI syntax:

aws-kinesis-firehose:streamName

with the following path and query parameters:

Path Parameters (1 parameters):

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

proxyHost (producer)

String

proxyPort (producer)

To define a proxy port when instantiating the Kinesis Firehose client

Integer

HTTPS

Protocol

region (producer)

The region in which Kinesis client needs to work. When using this parameter, the configuration will expect the capitalized name of the region (for example AP_EAST_1)You’ll need to use the name Regions.EU_WEST_1.name()

String

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

accessKey (security)

Amazon AWS Access Key

String

secretKey (security)

Amazon AWS Secret Key

String

Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-aws-kinesis-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

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

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");

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(…​).

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

Header Type Description

CamelAwsKinesisFirehoseRecordId

String

The record ID, as defined in Response Syntax

Automatic detection of AmazonKinesisFirehose client in registry

The component is capable of detecting the presence of an AmazonKinesisFirehose bean into the registry. If it’s the only instance of that type it will be used as client and you won’t have to define it as uri parameter. This may be really useful for smarter configuration of the endpoint.

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-kinesis</artifactId>
    <version>${camel-version}</version>
</dependency>

where ${camel-version} must be replaced by the actual version of Camel.
