camel-vm-kafka-connector sink configuration

Connector Description: Call another endpoint in the same CamelContext asynchronously.

When using camel-vm-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-vm-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.vm.CamelVmSinkConnector

The camel-vm sink connector supports 18 options, which are listed below.

Name Description Default Required Priority

camel.sink.path.name

Name of queue

null

true

HIGH

camel.sink.endpoint.size

The maximum capacity of the SEDA queue (i.e., the number of messages it can hold). Will by default use the defaultSize set on the SEDA component.

1000

false

MEDIUM

camel.sink.endpoint.blockWhenFull

Whether a thread that sends messages to a full SEDA queue will block until the queue’s capacity is no longer exhausted. By default, an exception will be thrown stating that the queue is full. By enabling this option, the calling thread will instead block and wait until the message can be accepted.

false

false

MEDIUM

camel.sink.endpoint.discardIfNoConsumers

Whether the producer should discard the message (do not add the message to the queue), when sending to a queue with no active consumers. Only one of the options discardIfNoConsumers and failIfNoConsumers can be enabled at the same time.

false

false

MEDIUM

camel.sink.endpoint.discardWhenFull

Whether a thread that sends messages to a full SEDA queue will be discarded. By default, an exception will be thrown stating that the queue is full. By enabling this option, the calling thread will give up sending and continue, meaning that the message was not sent to the SEDA queue.

false

false

MEDIUM

camel.sink.endpoint.failIfNoConsumers

Whether the producer should fail by throwing an exception, when sending to a queue with no active consumers. Only one of the options discardIfNoConsumers and failIfNoConsumers can be enabled at the same time.

false

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.offerTimeout

offerTimeout (in milliseconds) can be added to the block case when queue is full. You can disable timeout by using 0 or a negative value.

null

false

MEDIUM

camel.sink.endpoint.timeout

Timeout (in milliseconds) before a SEDA producer will stop waiting for an asynchronous task to complete. You can disable timeout by using 0 or a negative value.

30000L

false

MEDIUM

camel.sink.endpoint.waitForTaskToComplete

Option to specify whether the caller should wait for the async task to complete or not before continuing. The following three options are supported: Always, Never or IfReplyExpected. The first two values are self-explanatory. The last value, IfReplyExpected, will only wait if the message is Request Reply based. The default option is IfReplyExpected. One of: [Never] [IfReplyExpected] [Always]

"IfReplyExpected"

false

MEDIUM

camel.sink.endpoint.queue

Define the queue instance which will be used by the endpoint

null

false

MEDIUM

camel.component.vm.defaultBlockWhenFull

Whether a thread that sends messages to a full SEDA queue will block until the queue’s capacity is no longer exhausted. By default, an exception will be thrown stating that the queue is full. By enabling this option, the calling thread will instead block and wait until the message can be accepted.

false

false

MEDIUM

camel.component.vm.defaultDiscardWhenFull

Whether a thread that sends messages to a full SEDA queue will be discarded. By default, an exception will be thrown stating that the queue is full. By enabling this option, the calling thread will give up sending and continue, meaning that the message was not sent to the SEDA queue.

false

false

MEDIUM

camel.component.vm.defaultOfferTimeout

Whether a thread that sends messages to a full SEDA queue will block until the queue’s capacity is no longer exhausted. By default, an exception will be thrown stating that the queue is full. By enabling this option, where a configured timeout can be added to the block case. Utilizing the .offer(timeout) method of the underlining java queue

null

false

MEDIUM

camel.component.vm.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.component.vm.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.vm.defaultQueueFactory

Sets the default queue factory.

null

false

MEDIUM

camel.component.vm.queueSize

Sets the default maximum capacity of the SEDA queue (i.e., the number of messages it can hold).

1000

false

MEDIUM
