Ignite Messaging
Since Camel 2.17
Both producer and consumer are supported
The Ignite Messaging endpoint is one of camel-ignite endpoints which allows you to send and consume messages from an Ignite topic.
This endpoint supports producers (to send messages) and consumers (to receive messages).
Options
The Ignite Messaging component supports 6 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
configurationResource (common) |
The resource from where to load the configuration. It can be a: URL, String or InputStream type. |
Object |
|
ignite (common) |
To use an existing Ignite instance. |
Ignite |
|
igniteConfiguration (common) |
Allows the user to set a programmatic ignite configuration. |
IgniteConfiguration |
|
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 |
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 |
autowiredEnabled (advanced) |
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 |
boolean |
The Ignite Messaging endpoint is configured using URI syntax:
ignite-messaging:topic
with the following path and query parameters:
Query Parameters (9 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
propagateIncomingBodyIfNoReturnValue (common) |
Sets whether to propagate the incoming body if the return type of the underlying Ignite operation is void. |
true |
boolean |
treatCollectionsAsCacheObjects (common) |
Sets whether to treat Collections as cache objects or as Collections of items to insert/update/compute, etc. |
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 |
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. There are 3 enums and the value can be one of: InOnly, InOut, InOptionalOut |
ExchangePattern |
|
clusterGroupExpression (producer) |
The cluster group expression. |
ClusterGroupExpression |
|
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 |
sendMode (producer) |
The send mode to use. Possible values: UNORDERED, ORDERED. There are 2 enums and the value can be one of: ORDERED, UNORDERED |
UNORDERED |
IgniteMessagingSendMode |
timeout (producer) |
The timeout for the send operation when using ordered messages. |
Long |
Headers used
This endpoint uses the following headers:
| Header name | Constant | Expected type | Description |
|---|---|---|---|
CamelIgniteMessagingTopic |
IgniteConstants.IGNITE_MESSAGING_TOPIC |
String |
Allows you to dynamically change the topic to send messages to (producer). It also carries the topic on which a message was received (consumer). |
CamelIgniteMessagingUUID |
IgniteConstants.IGNITE_MESSAGING_UUID |
UUID |
This header is filled in with the UUID of the subscription when a message arrives (consumer). |
Spring Boot Auto-Configuration
When using ignite-messaging with 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 44 options, which are listed below.
