Chapter 42. Infinispan Embedded Since Camel 2.13 Both producer and consumer are supported This component allows you to interact with Infinispan distributed data grid / cache. Infinispan is an extremely scalable, highly available key / value data store and data grid platform written in Java. The camel-infinispan-embedded component includes the following features. Local Camel Consumer - Receives cache change notifications and sends them to be processed. This can be done synchronously or asynchronously, and is also supported with a replicated or distributed cache. Local Camel Producer - A producer creates and sends messages to an endpoint. The camel-infinispan producer uses GET , PUT , REMOVE , and CLEAR operations. The local producer is also supported with a replicated or distributed cache. The events are processed asynchronously. 42.1. Dependencies When using infinispan-embedded with Red Hat build of Camel 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-embedded-starter</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency> 42.2. URI format The producer allows sending messages to a local infinispan cache. The consumer allows listening for events from local infinispan cache. If no cache configuration is provided, embedded cacheContainer is created directly in the component. 42.3. Configuring Options Camel components are configured on two separate levels. component level endpoint level 42.3.1. 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 more. 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. 42.3.2. Configuring Endpoint Options Endpoints 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 done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java. Use Property Placeholders to configure options that 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. 42.4. Component Options The Infinispan Embedded component supports 20 options that are listed below. Name Description Default Type configuration (common) Component configuration. InfinispanEmbeddedConfiguration queryBuilder (common) Specifies the query builder. InfinispanQueryBuilder 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 clusteredListener (consumer) If true, the listener will be installed for the entire cluster. false boolean customListener (consumer) Returns the custom listener in use, if provided. InfinispanEmbeddedCustomListener 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: CACHE_ENTRY_ACTIVATED, CACHE_ENTRY_PASSIVATED, CACHE_ENTRY_VISITED, CACHE_ENTRY_LOADED, CACHE_ENTRY_EVICTED, CACHE_ENTRY_CREATED, CACHE_ENTRY_REMOVED, CACHE_ENTRY_MODIFIED, TRANSACTION_COMPLETED, TRANSACTION_REGISTERED, CACHE_ENTRY_INVALIDATED, CACHE_ENTRY_EXPIRED, DATA_REHASHED, TOPOLOGY_CHANGED, PARTITION_STATUS_CHANGED, PERSISTENCE_AVAILABILITY_CHANGED. String sync (consumer) If true, the consumer will receive notifications synchronously. true boolean 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 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 autowiredEnabled (advanced) Whether auto-wiring is enabled. This is used for automatic auto-wiring options (the option must be marked as auto-wired) 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. EmbeddedCacheManager cacheContainerConfiguration (advanced) Autowired The CacheContainer configuration. Used if the cacheContainer is not defined. Configuration configurationUri (advanced) An implementation specific URI for the CacheManager. String flags (advanced) A comma separated list of org.infinispan.context.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 42.5. Endpoint Options The Infinispan Embedded endpoint is configured using URI syntax. Following are the path and query parameters. 42.5.1. 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 42.5.2. Query Parameters (20 parameters) Name Description Default Type queryBuilder (common) Specifies the query builder. InfinispanQueryBuilder clusteredListener (consumer) If true, the listener will be installed for the entire cluster. false boolean customListener (consumer) Returns the custom listener in use, if provided.

The possible event types are: CACHE_ENTRY_ACTIVATED, CACHE_ENTRY_PASSIVATED, CACHE_ENTRY_VISITED, CACHE_ENTRY_LOADED, CACHE_ENTRY_EVICTED, CACHE_ENTRY_CREATED, CACHE_ENTRY_REMOVED, CACHE_ENTRY_MODIFIED, TRANSACTION_COMPLETED, TRANSACTION_REGISTERED, CACHE_ENTRY_INVALIDATED, CACHE_ENTRY_EXPIRED, DATA_REHASHED, TOPOLOGY_CHANGED, PARTITION_STATUS_CHANGED, PERSISTENCE_AVAILABILITY_CHANGED. String sync (consumer) If true, the consumer will receive notifications synchronously. true boolean bridgeErrorHandler (consumer (advanced)) 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 (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 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.

EmbeddedCacheManager cacheContainerConfiguration (advanced) Autowired The CacheContainer configuration. Used if the cacheContainer is not defined. Configuration configurationUri (advanced) An implementation specific URI for the CacheManager. String flags (advanced) A comma separated list of org.infinispan.context.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 42.6.

Spring Boot Auto-Configuration The component supports 17 options that are listed below. Name Description Default Type camel.component.infinispan-embedded.autowired-enabled 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 camel.component.infinispan-embedded.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 Boolean camel.component.infinispan-embedded.cache-container Specifies the cache Container to connect.
