camel-disruptor-kafka-connector source configuration

Connector description: Provides asynchronous SEDA behavior using LMAX Disruptor.

When using camel-disruptor-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-disruptor-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.disruptor.CamelDisruptorSourceConnector

The camel-disruptor source connector supports 14 options, which are listed below.

Name Description Default Required Priority

camel.source.path.name

Name of queue

null

true

HIGH

camel.source.endpoint.size

The maximum capacity of the Disruptors ringbuffer Will be effectively increased to the nearest power of two. Notice: Mind if you use this option, then its the first endpoint being created with the queue name, that determines the size. To make sure all endpoints use same size, then configure the size option on all of them, or the first endpoint being created.

1024

false

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

false

MEDIUM

camel.source.endpoint.concurrentConsumers

Number of concurrent threads processing exchanges.

1

false

MEDIUM

camel.source.endpoint.multipleConsumers

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

false

false

MEDIUM

camel.source.endpoint.waitStrategy

Defines the strategy used by consumer threads to wait on new exchanges to be published. The options allowed are:Blocking, Sleeping, BusySpin and Yielding. One of: [Blocking] [Sleeping] [BusySpin] [Yielding]

"Blocking"

false

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.

null

false

MEDIUM

camel.source.endpoint.exchangePattern

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

null

false

MEDIUM

camel.component.disruptor.bufferSize

To configure the ring buffer size

1024

false

MEDIUM

camel.component.disruptor.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

false

MEDIUM

camel.component.disruptor.defaultConcurrent Consumers

To configure the default number of concurrent consumers

1

false

MEDIUM

camel.component.disruptor.defaultMultipleConsumers

To configure the default value for multiple consumers

false

false

MEDIUM

camel.component.disruptor.defaultWaitStrategy

To configure the default value for DisruptorWaitStrategy The default value is Blocking. One of: [Blocking] [Sleeping] [BusySpin] [Yielding]

"Blocking"

false

MEDIUM

camel.component.disruptor.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
