camel-jpa-kafka-connector sink configuration

When using camel-jpa-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-jpa-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.jpa.CamelJpaSinkConnector

The camel-jpa sink connector supports 25 options, which are listed below.

Name Description Default Priority

camel.sink.path.entityType

Entity class name

null

HIGH

camel.sink.endpoint.joinTransaction

The camel-jpa component will join transaction by default. You can use this option to turn this off, for example if you use LOCAL_RESOURCE and join transaction doesn’t work with your JPA provider. This option can also be set globally on the JpaComponent, instead of having to set it on all endpoints.

true

MEDIUM

camel.sink.endpoint.maximumResults

Set the maximum number of results to retrieve on the Query.

-1

MEDIUM

camel.sink.endpoint.namedQuery

To use a named query.

null

MEDIUM

camel.sink.endpoint.nativeQuery

To use a custom native query. You may want to use the option resultClass also when using native queries.

null

MEDIUM

camel.sink.endpoint.persistenceUnit

The JPA persistence unit used by default.

"camel"

HIGH

camel.sink.endpoint.query

To use a custom query.

null

MEDIUM

camel.sink.endpoint.resultClass

Defines the type of the returned payload (we will call entityManager.createNativeQuery(nativeQuery, resultClass) instead of entityManager.createNativeQuery(nativeQuery)). Without this option, we will return an object array. Only has an affect when using in conjunction with native query when consuming data.

null

MEDIUM

camel.sink.endpoint.findEntity

If enabled then the producer will find a single entity by using the message body as key and entityType as the class type. This can be used instead of a query to find a single entity.

false

MEDIUM

camel.sink.endpoint.flushOnSend

Flushes the EntityManager after the entity bean has been persisted.

true

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

MEDIUM

camel.sink.endpoint.remove

Indicates to use entityManager.remove(entity).

false

MEDIUM

camel.sink.endpoint.useExecuteUpdate

To configure whether to use executeUpdate() when producer executes a query. When you use INSERT, UPDATE or DELETE statement as a named query, you need to specify this option to 'true'.

null

MEDIUM

camel.sink.endpoint.usePersist

Indicates to use entityManager.persist(entity) instead of entityManager.merge(entity). Note: entityManager.persist(entity) doesn’t work for detached entities (where the EntityManager has to execute an UPDATE instead of an INSERT query)!

false

MEDIUM

camel.sink.endpoint.usePassedInEntityManager

If set to true, then Camel will use the EntityManager from the header JpaConstants.ENTITY_MANAGER instead of the configured entity manager on the component/endpoint. This allows end users to control which entity manager will be in use.

false

MEDIUM

camel.sink.endpoint.basicPropertyBinding

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

MEDIUM

camel.sink.endpoint.entityManagerProperties

Additional properties for the entity manager to use.

null

MEDIUM

camel.sink.endpoint.sharedEntityManager

Whether to use Spring’s SharedEntityManager for the consumer/producer. Note in most cases joinTransaction should be set to false as this is not an EXTENDED EntityManager.

false

MEDIUM

camel.sink.endpoint.synchronous

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

MEDIUM

camel.component.jpa.entityManagerFactory

To use the EntityManagerFactory. This is strongly recommended to configure.

null

MEDIUM

camel.component.jpa.joinTransaction

The camel-jpa component will join transaction by default. You can use this option to turn this off, for example if you use LOCAL_RESOURCE and join transaction doesn’t work with your JPA provider. This option can also be set globally on the JpaComponent, instead of having to set it on all endpoints.

true

MEDIUM

camel.component.jpa.sharedEntityManager

Whether to use Spring’s SharedEntityManager for the consumer/producer. Note in most cases joinTransaction should be set to false as this is not an EXTENDED EntityManager.

false

MEDIUM

camel.component.jpa.transactionManager

To use the PlatformTransactionManager for managing transactions.

null

MEDIUM

camel.component.jpa.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

MEDIUM

camel.component.jpa.basicPropertyBinding

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false
