camel-seda-kafka-connector source configuration

Connector Description: Asynchronously call another endpoint from any Camel Context in the same JVM.

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

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

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

connector.class=org.apache.camel.kafkaconnector.seda.CamelSedaSourceConnector

The camel-seda source connector supports 16 options, which are listed below.

Name Description Default Priority

camel.source.path.name

Required Name of queue.

HIGH

camel.source.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

MEDIUM

camel.source.endpoint.bridgeErrorHandler

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

MEDIUM

camel.source.endpoint.concurrentConsumers

Number of concurrent threads processing exchanges.

1

MEDIUM

camel.source.endpoint.exceptionHandler

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

MEDIUM

camel.source.endpoint.exchangePattern

Sets the exchange pattern when the consumer creates an exchange. One of: [InOnly] [InOut] [InOptionalOut].

Enum values:

  • InOnly

  • InOut

  • InOptionalOut

MEDIUM

camel.source.endpoint.limitConcurrentConsumers

Whether to limit the number of concurrentConsumers to the maximum of 500. By default, an exception will be thrown if an endpoint is configured with a greater number. You can disable that check by turning this option off.

true

MEDIUM

camel.source.endpoint.multipleConsumers

Specifies whether multiple consumers are allowed. If enabled, you can use SEDA for Publish-Subscribe messaging. That is, you can send a message to the SEDA queue and have each consumer receive a copy of the message. When enabled, this option should be specified on every consumer endpoint.

false

MEDIUM

camel.source.endpoint.pollTimeout

The timeout used when polling. When a timeout occurs, the consumer can check whether it is allowed to continue running. Setting a lower value allows the consumer to react more quickly upon shutdown.

1000

MEDIUM

camel.source.endpoint.purgeWhenStopping

Whether to purge the task queue when stopping the consumer/route. This allows to stop faster, as any pending messages on the queue is discarded.

false

MEDIUM

camel.source.endpoint.queue

Define the queue instance which will be used by the endpoint.

MEDIUM

camel.component.seda.bridgeErrorHandler

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

MEDIUM

camel.component.seda.concurrentConsumers

Sets the default number of concurrent threads processing exchanges.

1

MEDIUM

camel.component.seda.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.seda.defaultQueueFactory

Sets the default queue factory.

MEDIUM

camel.component.seda.queueSize

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

1000

MEDIUM

The camel-seda source connector has no converters out of the box.

The camel-seda source connector has no transforms out of the box.

The camel-seda source connector has no aggregation strategies out of the box.
