AWS 2 Eventbridge

Since Camel 3.6

Only producer is supported

The AWS2 Eventbridge component supports assumeRole operation. AWS Eventbridge.

Prerequisites

You must have a valid Amazon Web Services developer account, and be signed up to use Amazon Eventbridge. More information is available at Amazon Eventbridge.

The AWS2 Eventbridge component is not supported in OSGI

To create a rule that triggers on an action by an AWS service that does not emit events, you can base the rule on API calls made by that service. The API calls are recorded by AWS CloudTrail, so you’ll need to have CloudTrail enabled. For more information Services Supported by CloudTrail Event History.

URI Format

aws2-eventbridge://label[?options]

You can append query options to the URI in the following format, ?options=value&option2=value&…​

URI Options

The AWS 2 Eventbridge component supports 15 options, which are listed below.

Name Description Default Type

autoDiscoverClient (common)

Setting the autoDiscoverClient mechanism, if true, the component will look for a client instance in the registry automatically otherwise it will skip that checking.

true

boolean

configuration (producer)

Component configuration

eventbridgeClient (producer)

To use a existing configured AWS Eventbridge as client

EventBridgeClient

String

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

operation (producer)

Required The operation to perform. There are 10 enums and the value can be one of: putRule, putTargets, removeTargets, deleteRule, enableRule, disableRule, describeRule, listRules, listTargetsByRule, listRuleNamesByTarget

AWS2-Eventbridge Producer operations

Camel-AWS2-Eventbridge component provides the following operation on the producer side:

  • putRule

  • putTargets

  • removeTargets

  • deleteRule

  • enableRule

  • disableRule

  • listRules

  • describeRule

  • listTargetsByRule

  • listRuleNamesByTarget

  • PutRule: this operation create a rule related to an eventbus

  from("direct:putRule").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(EventbridgeConstants.RULE_NAME, "firstrule");
      }
  })
  .to("aws2-eventbridge://test?operation=putRule&eventPatternFile=file:src/test/resources/eventpattern.json")
  .to("mock:result");

This operation will create a rule named firstrule and it will use a json file for defining the EventPattern.

  • PutTargets: this operation will add a target to the rule

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {

          Target target = Target.builder().id("sqs-queue").arn("arn:aws:sqs:eu-west-1:780410022472:camel-connector-test")
                .build();
          List<Target> targets = new ArrayList<Target>();
          targets.add(target);
          exchange.getIn().setHeader(EventbridgeConstants.TARGETS, targets);
      }

      }
  })
  .to("aws2-eventbridge://test?operation=enableRule")
  .to("mock:result");

This operation will enable the firstrule rule from the test eventbus.

  • DisableRule: this operation will disable a rule related to an eventbus

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(EventbridgeConstants.RULE_NAME, "firstrule");
      }
  })
  .to("aws2-eventbridge://test?operation=disableRule")
  .to("mock:result");

This operation will disable the firstrule rule from the test eventbus.

  • ListRules: this operation will list all the rules related to an eventbus with prefix first

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(EventbridgeConstants.RULE_NAME_PREFIX, "first");
      }
  })
  .to("aws2-eventbridge://test?operation=listRules")
  .to("mock:result");

This operation will list all the rules with prefix first from the test eventbus.

  • DescribeRule: this operation will describe a specified rule related to an eventbus

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(EventbridgeConstants.RULE_NAME, "firstrule");
      }
  })
  .to("aws2-eventbridge://test?operation=describeRule")
  .to("mock:result");

This operation will describe the firstrule rule from the test eventbus.

  • ListTargetsByRule: this operation will return a list of targets associated with a rule

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(EventbridgeConstants.RULE_NAME, "firstrule");
      }
  })
  .to("aws2-eventbridge://test?operation=listTargetsByRule")
  .to("mock:result");

this operation will return a list of targets associated with the firstrule rule.

  • ListRuleNamesByTarget: this operation will return a list of rule associated with a target

  from("direct:start").process(new Processor() {

      @Override
      public void process(Exchange exchange) throws Exception {
          exchange.getIn().setHeader(EventbridgeConstants.TARGET_ARN, "firstrule");
      }
  })
  .to("aws2-eventbridge://test?operation=listRuleNamesByTarget")
  .to("mock:result");

this operation will return a list of rule associated with a target.

Updating the rule

To update a rule you’ll need to perform the putRule operation again. There is not explicit update rule operation in the Java SDK.

Automatic detection of EventbridgeClient client in registry

The component is capable of detecting the presence of an EventbridgeClient 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, like the example above. 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-aws2-eventbridge</artifactId>
    <version>${camel-version}</version>
</dependency>

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

Spring Boot Auto-Configuration

When using aws2-eventbridge with 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-aws2-eventbridge-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 15 options, which are listed below.

This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

EventBridgeClient

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.
