camel-cometd-kafka-connector sink configuration

Connector Description: Offers publish/subscribe, peer-to-peer (via a server), and RPC style messaging using the CometD/Bayeux protocol.

When using camel-cometd-kafka-connector as sink make sure to use the following Maven dependency to have support for the connector:

<dependency>
  <groupId>org.apache.camel.kafkaconnector</groupId>
  <artifactId>camel-cometd-kafka-connector</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel Kafka connector version -->
</dependency>

To use this sink connector in Kafka connect you’ll need to set the following connector.class

connector.class=org.apache.camel.kafkaconnector.cometd.CamelCometdSinkConnector

The camel-cometd sink connector supports 24 options, which are listed below.

Name Description Default Priority

camel.sink.path.host

Required Hostname.

HIGH

camel.sink.path.port

Required Host port number.

HIGH

camel.sink.path.channelName

Required The channelName represents a topic that can be subscribed to by the Camel endpoints.

HIGH

camel.sink.endpoint.allowedOrigins

The origins domain that support to cross, if the crosssOriginFilterOn is true.

"*"

MEDIUM

camel.sink.endpoint.baseResource

The root directory for the web resources or classpath. Use the protocol file: or classpath: depending if you want that the component loads the resource from file system or classpath. Classpath is required for OSGI deployment where the resources are packaged in the jar.

MEDIUM

camel.sink.endpoint.crossOriginFilterOn

If true, the server will support for cross-domain filtering.

false

MEDIUM

camel.sink.endpoint.filterPath

The filterPath will be used by the CrossOriginFilter, if the crosssOriginFilterOn is true.

MEDIUM

camel.sink.endpoint.interval

The client side poll timeout in milliseconds. How long a client will wait between reconnects.

MEDIUM

camel.sink.endpoint.jsonCommented

If true, the server will accept JSON wrapped in a comment and will generate JSON wrapped in a comment. This is a defence against Ajax Hijacking.

true

MEDIUM

camel.sink.endpoint.logLevel

Logging level. 0=none, 1=info, 2=debug. One of: [0] [1] [2].

Enum values:

  • 0

  • 1

  • 2

1

MEDIUM

camel.sink.endpoint.maxInterval

The max client side poll timeout in milliseconds. A client will be removed if a connection is not received in this time.

30000

MEDIUM

camel.sink.endpoint.multiFrameInterval

The client side poll timeout, if multiple connections are detected from the same browser.

1500

MEDIUM

camel.sink.endpoint.timeout

The server side poll timeout in milliseconds. This is how long the server will hold a reconnect request before responding.

240000

MEDIUM

camel.sink.endpoint.disconnectLocalSession

Whether to disconnect local sessions after publishing a message to its channel. Disconnecting local session is needed as they are not swept by default by CometD, and therefore you can run out of memory.

false

MEDIUM

camel.sink.endpoint.lazyStartProducer

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

MEDIUM

camel.component.cometd.lazyStartProducer

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

MEDIUM

camel.component.cometd.autowiredEnabled

Whether autowiring is enabled. 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.

true

MEDIUM

camel.component.cometd.extensions

To use a list of custom BayeuxServer.Extension that allows modifying incoming and outgoing requests.

MEDIUM

camel.component.cometd.securityPolicy

To use a custom configured SecurityPolicy to control authorization.

MEDIUM

camel.component.cometd.sslContextParameters

To configure security using SSLContextParameters.

MEDIUM

camel.component.cometd.sslKeyPassword

The password for the keystore when using SSL.

MEDIUM

camel.component.cometd.sslKeystore

The path to the keystore.

MEDIUM

camel.component.cometd.sslPassword

The password when using SSL.

MEDIUM

camel.component.cometd.useGlobalSslContextParameters

Enable usage of global SSL context parameters.

false

MEDIUM
