Chapter 29. Infinispan Both producer and consumer are supported This component allows you to interact with Infinispan distributed data grid / cache using the Hot Rod procol. Infinispan is an extremely scalable, highly available key/value data store and data grid platform written in Java. If you use Maven, you must add the following dependency to your pom.xml : <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-infinispan</artifactId> <version>{CamelSBVersion}</version> <!-- use the same version as your Camel core version --> </dependency> 29.1. URI format The producer allows sending messages to a remote cache using the HotRod protocol. The consumer allows listening for events from a remote cache using the HotRod protocol. 29.2. Configuring Options Camel components are configured on two separate levels: component level endpoint level 29.2.1. Configuring Component Options The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth. Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all. Configuring components can be done with the Component DSL , in a configuration file (application.properties|yaml), or directly with Java code. 29.2.2. Configuring Endpoint Options Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both. Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL as a type safe way of configuring endpoints. A good practice when configuring options is to use Property Placeholders , which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse. The following two sections lists all the options, firstly for the component followed by the endpoint. 29.3. Component Options The Infinispan component supports 26 options, which are listed below. Name Description Default Type configuration (common) Component configuration. InfinispanRemoteConfiguration hosts (common) Specifies the host of the cache on Infinispan instance. String queryBuilder (common) Specifies the query builder. InfinispanQueryBuilder secure (common) Define if we are connecting to a secured Infinispan instance. 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 customListener (consumer) Returns the custom listener in use, if provided. InfinispanRemoteCustomListener eventTypes (consumer) Specifies the set of event types to register by the consumer.Multiple event can be separated by comma. The possible event types are: CLIENT_CACHE_ENTRY_CREATED, CLIENT_CACHE_ENTRY_MODIFIED, CLIENT_CACHE_ENTRY_REMOVED, CLIENT_CACHE_ENTRY_EXPIRED, CLIENT_CACHE_FAILOVER. String defaultValue (producer) Set a specific default value for some producer operations. Object key (producer) Set a specific key for producer operations. Object 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 oldValue (producer) Set a specific old value for some producer operations. Object operation (producer) The operation to perform. Enum values: PUT PUTASYNC PUTALL PUTALLASYNC PUTIFABSENT PUTIFABSENTASYNC GET GETORDEFAULT CONTAINSKEY CONTAINSVALUE REMOVE REMOVEASYNC REPLACE REPLACEASYNC SIZE CLEAR CLEARASYNC QUERY STATS COMPUTE COMPUTEASYNC PUT InfinispanOperation value (producer) Set a specific value for producer operations. Object password ( security) Define the password to access the infinispan instance. String saslMechanism ( security) Define the SASL Mechanism to access the infinispan instance. String securityRealm ( security) Define the security realm to access the infinispan instance. String securityServerName ( security) Define the security server name to access the infinispan instance. String username ( security) Define the username to access the infinispan instance. String 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 cacheContainer (advanced) Autowired Specifies the cache Container to connect. RemoteCacheManager cacheContainerConfiguration (advanced) Autowired The CacheContainer configuration. Used if the cacheContainer is not defined. Configuration configurationProperties (advanced) Implementation specific properties for the CacheManager. Map configurationUri (advanced) An implementation specific URI for the CacheManager. String flags (advanced) A comma separated list of org.infinispan.client.hotrod.Flag to be applied by default on each cache invocation. String remappingFunction (advanced) Set a specific remappingFunction to use in a compute operation. BiFunction resultHeader (advanced) Store the operation result in a header instead of the message body. By default, resultHeader == null and the query result is stored in the message body, any existing content in the message body is discarded. If resultHeader is set, the value is used as the name of the header to store the query result and the original message body is preserved. This value can be overridden by an in message header named: CamelInfinispanOperationResultHeader. String 29.4. Endpoint Options The Infinispan endpoint is configured using URI syntax: with the following path and query parameters: 29.4.1. Path Parameters (1 parameters) Name Description Default Type cacheName (common) Required The name of the cache to use. Use current to use the existing cache name from the currently configured cached manager. Or use default for the default cache manager name. String 29.4.2. Query Parameters (26 parameters) Name Description Default Type hosts (common) Specifies the host of the cache on Infinispan instance. String queryBuilder (common) Specifies the query builder. InfinispanQueryBuilder secure (common) Define if we are connecting to a secured Infinispan instance. 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 customListener (consumer) Returns the custom listener in use, if provided. InfinispanRemoteCustomListener eventTypes (consumer) Specifies the set of event types to register by the consumer.Multiple event can be separated by comma. The possible event types are: CLIENT_CACHE_ENTRY_CREATED, CLIENT_CACHE_ENTRY_MODIFIED, CLIENT_CACHE_ENTRY_REMOVED, CLIENT_CACHE_ENTRY_EXPIRED, CLIENT_CACHE_FAILOVER. String exceptionHandler (consumer (advanced)) 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 (advanced)) Sets the exchange pattern when the consumer creates an exchange. Enum values: InOnly InOut InOptionalOut ExchangePattern defaultValue (producer) Set a specific default value for some producer operations. Object key (producer) Set a specific key for producer operations. Object lazyStartProducer (producer) Whether the producer should be started lazy (on the first message).

Examples Put a key/value into a named cache: from("direct:start") .setHeader(InfinispanConstants.OPERATION).constant(InfinispanOperation.PUT) (1) .setHeader(InfinispanConstants.KEY).constant("123") (2) .to("infinispan:myCacheName&cacheContainer=#cacheContainer"); (3) Where, 1 - Set the operation to perform 2 - Set the key used to identify the element in the cache 3 - Use the configured cache manager cacheContainer from the registry to put an element to the cache named myCacheName It is possible to configure the lifetime and/or the idle time before the entry expires and gets evicted from the cache, as example: from("direct:start") .setHeader(InfinispanConstants.OPERATION).constant(InfinispanOperation.GET) .setHeader(InfinispanConstants.KEY).constant("123") .setHeader(InfinispanConstants.LIFESPAN_TIME).constant(100L) (1) .setHeader(InfinispanConstants.LIFESPAN_TIME_UNIT.constant(TimeUnit.MILLISECONDS.toString()) (2) .to("infinispan:myCacheName"); where, 1 - Set the lifespan of the entry 2 - Set the time unit for the lifespan Queries from("direct:start") .setHeader(InfinispanConstants.OPERATION, InfinispanConstants.QUERY) .setHeader(InfinispanConstants.QUERY_BUILDER, new InfinispanQueryBuilder() { @Override public Query build(QueryFactory<Query> qf) { return qf.from(User.class).having("name").like("%abc%").build(); } }) .to("infinispan:myCacheName?cacheContainer=#cacheManager") ; Note The .proto descriptors for domain objects must be registered with the remote Data Grid server, see Remote Query Example in the official Infinispan documentation. Custom Listeners from("infinispan://?cacheContainer=#cacheManager&customListener=#myCustomListener") .to("mock:result"); The instance of myCustomListener must exist and Camel should be able to look it up from the Registry . Users are encouraged to extend the org.apache.camel.component.infinispan.remote.InfinispanRemoteCustomListener class and annotate the resulting class with @ClientListener which can be found found in package org.infinispan.client.hotrod.annotation . 29.8. Using the Infinispan based idempotent repository In this section we will use the Infinispan based idempotent repository. Java Example InfinispanRemoteConfiguration conf = new InfinispanRemoteConfiguration(); (1) conf.setHosts("localhost:1122") InfinispanRemoteIdempotentRepository repo = new InfinispanRemoteIdempotentRepository("idempotent"); (2) repo.setConfiguration(conf); context.addRoutes(new RouteBuilder() { @Override public void configure() { from("direct:start") .idempotentConsumer(header("MessageID"), repo) (3) .to("mock:result"); } }); where, 1 - Configure the cache 2 - Configure the repository bean 3 - Set the repository to the route XML Example <bean id="infinispanRepo" class="org.apache.camel.component.infinispan.remote.InfinispanRemoteIdempotentRepository" destroy-method="stop"> <constructor-arg value="idempotent"/> (1) <property name="configuration"> (2) <bean class="org.apache.camel.component.infinispan.remote.InfinispanRemoteConfiguration"> <property name="hosts" value="localhost:11222"/> </bean> </property> </bean> <camelContext xmlns="http://camel.apache.org/schema/spring"> <route> <from uri="direct:start" /> <idempotentConsumer messageIdRepositoryRef="infinispanRepo"> (3) <header>MessageID</header> <to uri="mock:result" /> </idempotentConsumer> </route> </camelContext> where, 1 - Set the name of the cache that will be used by the repository 2 - Configure the repository bean 3 - Set the repository to the route 29.9. Using the Infinispan based aggregation repository In this section we will use the Infinispan based aggregation repository. Java Example InfinispanRemoteConfiguration conf = new InfinispanRemoteConfiguration(); (1) conf.setHosts("localhost:1122") InfinispanRemoteAggregationRepository repo = new InfinispanRemoteAggregationRepository(); (2) repo.setCacheName("aggregation"); repo.setConfiguration(conf); context.addRoutes(new RouteBuilder() { @Override public void configure() { from("direct:start") .aggregate(header("MessageID")) .completionSize(3) .aggregationRepository(repo) (3) .aggregationStrategyRef("myStrategy") .to("mock:result"); } }); where, 1 - Configure the cache 2 - Create the repository bean 3 - Set the repository to the route XML Example <bean id="infinispanRepo" class="org.apache.camel.component.infinispan.remote.InfinispanRemoteAggregationRepository" destroy-method="stop"> <constructor-arg value="aggregation"/> (1) <property name="configuration"> (2) <bean class="org.apache.camel.component.infinispan.remote.InfinispanRemoteConfiguration"> <property name="hosts" value="localhost:11222"/> </bean> </property> </bean> <camelContext xmlns="http://camel.apache.org/schema/spring"> <route> <from uri="direct:start" /> <aggregate strategyRef="myStrategy" completionSize="3" aggregationRepositoryRef="infinispanRepo"> (3) <correlationExpression> <header>MessageID</header> </correlationExpression> <to uri="mock:result"/> </aggregate> </route> </camelContext> where, 1 - Set the name of the cache that will be used by the repository 2 - Configure the repository bean 3 - Set the repository to the route Note With the release of Infinispan 11, it is required to set the encoding configuration on any cache created. This is critical for consuming events too. For more information have a look at Data Encoding and MediaTypes in the official Infinispan documentation. 29.10. Spring Boot Auto-Configuration When using infinispan 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-infinispan-starter</artifactId> </dependency> The component supports 23 options, which are listed below.

String camel.component.infinispan.hosts Specifies the host of the cache on Infinispan instance. String camel.component.infinispan.lazy-start-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 camel.component.infinispan.operation The operation to perform.
