camel-websocket-kafka-connector sink configuration

Connector Description: Expose websocket endpoints using Jetty.

When using camel-websocket-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-websocket-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.websocket.CamelWebsocketSinkConnector

The camel-websocket sink connector supports 29 options, which are listed below.

Name Description Default Required Priority

camel.sink.path.host

The hostname. The default value is 0.0.0.0. Setting this option on the component will use the component configured value as default.

"0.0.0.0"

false

MEDIUM

camel.sink.path.port

The port number. The default value is 9292. Setting this option on the component will use the component configured value as default.

"9292"

false

MEDIUM

camel.sink.path.resourceUri

Name of the websocket channel to use

null

true

HIGH

camel.sink.endpoint.maxBinaryMessageSize

Can be used to set the size in bytes that the websocket created by the websocketServlet may be accept before closing. (Default is -1 - or unlimited)

"-1"

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

false

MEDIUM

camel.sink.endpoint.sendTimeout

Timeout in millis when sending to a websocket channel. The default timeout is 30000 (30 seconds).

"30000"

false

MEDIUM

camel.sink.endpoint.sendToAll

To send to all websocket subscribers. Can be used to configure on endpoint level, instead of having to use the WebsocketConstants.SEND_TO_ALL header on the message.

null

false

MEDIUM

camel.sink.endpoint.bufferSize

Set the buffer size of the websocketServlet, which is also the max frame byte size (default 8192)

"8192"

false

MEDIUM

camel.sink.endpoint.maxIdleTime

Set the time in ms that the websocket created by the websocketServlet may be idle before closing. (default is 300000)

"300000"

false

MEDIUM

camel.sink.endpoint.maxTextMessageSize

Can be used to set the size in characters that the websocket created by the websocketServlet may be accept before closing.

null

false

MEDIUM

camel.sink.endpoint.minVersion

Can be used to set the minimum protocol version accepted for the websocketServlet. (Default 13 - the RFC6455 version)

"13"

false

MEDIUM

camel.sink.endpoint.allowedOrigins

The CORS allowed origins. Use to allow all.

null

false

MEDIUM

camel.sink.endpoint.crossOriginFilterOn

Whether to enable CORS

false

false

MEDIUM

camel.sink.endpoint.filterPath

Context path for filtering CORS

null

false

MEDIUM

camel.sink.endpoint.enableJmx

If this option is true, Jetty JMX support will be enabled for this endpoint. See Jetty JMX support for more details.

false

false

MEDIUM

camel.sink.endpoint.sslContextParameters

To configure security using SSLContextParameters

null

false

MEDIUM

camel.component.websocket.host

The hostname. The default value is 0.0.0.0

"0.0.0.0"

false

MEDIUM

camel.component.websocket.port

The port number. The default value is 9292

"9292"

false

MEDIUM

camel.component.websocket.lazyStartProducer

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

false

MEDIUM

camel.component.websocket.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

false

MEDIUM

camel.component.websocket.enableJmx

If this option is true, Jetty JMX support will be enabled for this endpoint. See Jetty JMX support for more details.

false

false

MEDIUM

camel.component.websocket.maxThreads

To set a value for maximum number of threads in server thread pool. MaxThreads/minThreads or threadPool fields are required due to switch to Jetty9. The default values for maxThreads is 1 2 noCores.

null

false

MEDIUM

camel.component.websocket.minThreads

To set a value for minimum number of threads in server thread pool. MaxThreads/minThreads or threadPool fields are required due to switch to Jetty9. The default values for minThreads is 1.

null

false

MEDIUM

camel.component.websocket.threadPool

To use a custom thread pool for the server. MaxThreads/minThreads or threadPool fields are required due to switch to Jetty9.

Enable usage of global SSL context parameters.
