camel-hazelcast-seda-kafka-connector source configuration

Connector Description: Asynchronously send/receive Exchanges between Camel routes running on potentially distinct JVMs/hosts backed by Hazelcast BlockingQueue.

When using camel-hazelcast-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-hazelcast-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.hazelcastseda.CamelHazelcastsedaSourceConnector

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

Name Description Default Priority

camel.source.path.cacheName

Required The name of the cache.

HIGH

camel.source.endpoint.defaultOperation

To specify a default operation to use, if no operation header has been provided. One of: [put] [delete] [get] [update] [query] [getAll] [clear] [putIfAbsent] [allAll] [removeAll] [retainAll] [evict] [evictAll] [valueCount] [containsKey] [containsValue] [keySet] [removevalue] [increment] [decrement] [setvalue] [destroy] [compareAndSet] [getAndAdd] [add] [offer] [peek] [poll] [remainingCapacity] [drainTo] [removeIf] [take] [publish] [readOnceHeal] [readOnceTail] [capacity].

Enum values:

  • update

  • query

  • getAll

  • clear

  • allAll

  • removeAll

  • retainAll

  • evict

  • evictAll

  • valueCount

  • containsKey

  • containsValue

  • keySet

  • removevalue

  • increment

  • offer

  • peek

MEDIUM

camel.source.endpoint.hazelcastInstance

The hazelcast instance reference which can be used for hazelcast endpoint.

MEDIUM

camel.source.endpoint.hazelcastInstanceName

The hazelcast instance reference name which can be used for hazelcast endpoint. If you don’t specify the instance reference, camel use the default hazelcast instance from the camel-hazelcast instance.

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.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.concurrentConsumers

To use concurrent consumers polling from the SEDA queue.

1

MEDIUM

camel.source.endpoint.onErrorDelay

Milliseconds before consumer continues polling after an error has occurred.

1000

MEDIUM

camel.source.endpoint.pollTimeout

The timeout used when consuming from the SEDA queue. 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.transacted

If set to true then the consumer runs in transaction mode, where the messages in the seda queue will only be removed if the transaction commits, which happens when the processing is complete.

false

MEDIUM

camel.source.endpoint.transferExchange

If set to true the whole Exchange will be transfered. If header or body contains not serializable objects, they will be skipped.

false

MEDIUM

camel.component.hazelcast-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.hazelcast-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.hazelcast-seda.hazelcastInstance

The hazelcast instance reference which can be used for hazelcast endpoint. If you don’t specify the instance reference, camel use the default hazelcast instance from the camel-hazelcast instance.

MEDIUM

camel.component.hazelcast-seda.hazelcastMode

The hazelcast mode reference which kind of instance should be used. If you don’t specify the mode, then the node mode will be the default.

"node"

MEDIUM

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