Ignite Events Component

Since Camel 2.17

Only consumer is supported

The Ignite Events endpoint is one of camel-ignite endpoints which allows you to receive events from the Ignite cluster by creating a local event listener.

This endpoint only supports consumers. The Exchanges created by this consumer put the received Event object into the body of the IN message.

Options

The Ignite Events component supports 6 options, which are listed below.

Name Description Default Type

ignite (consumer)

Sets the Ignite instance.

Ignite

configurationResource (consumer)

Sets the resource from where to load the configuration. It can be a: URI, String (URI) or an InputStream.

Object

igniteConfiguration (consumer)

Allows the user to set a programmatic IgniteConfiguration.

IgniteConfiguration

basicPropertyBinding (advanced)

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

false

boolean

lazyStartProducer (producer)

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

boolean

bridgeErrorHandler (consumer)

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

boolean

The Ignite Events endpoint is configured using URI syntax:

ignite-events:endpointId

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

endpointId

The endpoint ID (not used).

String

Query Parameters (9 parameters):

Name Description Default Type

bridgeErrorHandler (consumer)

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

boolean

clusterGroupExpression (consumer)

The cluster group expression.

ClusterGroupExpression

events (consumer)

The event types to subscribe to as a comma-separated string of event constants as defined in EventType. For example: EVT_CACHE_ENTRY_CREATED,EVT_CACHE_OBJECT_REMOVED,EVT_IGFS_DIR_CREATED.

EVTS_ALL

String

propagateIncomingBodyIfNo ReturnValue (consumer)

Sets whether to propagate the incoming body if the return type of the underlying Ignite operation is void.

true

boolean

treatCollectionsAsCache Objects (consumer)

Sets whether to treat Collections as cache objects or as Collections of items to insert/update/compute, etc.

false

boolean

exceptionHandler (consumer)

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.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange.

ExchangePattern

basicPropertyBinding (advanced)

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

false

boolean

synchronous (advanced)

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

false

boolean

Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-ignite-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 7 options, which are listed below.

false

Boolean

camel.component.ignite-events.bridge-error-handler

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
