:supportLevel: Stable
:component-header: Both producer and consumer are supported
//Manually maintained attributes

*Since Camel {since}*

*{component-header}*

This component allows you to interact with
http://infinispan.org/[Infinispan] distributed data grid / cache.
Infinispan is an extremely scalable, highly available key/value data
store and data grid platform written in Java.

Infinispan requires at least Java 8.

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.

If you use Maven, you must add the following dependency to your `pom.xml`:

[source,xml]
------------------------------------------------------------
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-infinispan-embedded</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>
------------------------------------------------------------

== URI format

[source,java]
-------------------------------
infinispan-embedded://cacheName?[options]
-------------------------------

== URI Options

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.

// component options: START
The Infinispan Embedded component supports 20 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| 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'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. There are 21 enums and the value can be one of: 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 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 |  | 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

== Examples

* Put a key/value into a named cache:
+
[source,java]
----
from("direct:start")
    .setHeader(InfinispanConstants.OPERATION).constant(InfinispanOperation.PUT) // <1>
    .setHeader(InfinispanConstants.KEY).constant("123") // <2>
    .to("infinispan:myCacheName&cacheContainer=#cacheContainer"); // <3>
----
<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:
+
[source,java,options="nowrap"]
----
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");
----
<1> Set the lifespan of the entry
<2> Set the time unit for the lifespan

* Queries
+
[source,java,options="nowrap"]
----
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") ;
----
+

* Custom Listeners
+
[source,java,options="nowrap"]
----
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.embedded.InfinispanEmbeddedCustomListener` class and annotate the resulting class with `@Listener` which can be found found in package `org.infinispan.notifications`.

[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 https://infinispan.org/docs/stable/titles/developing/developing.html#data_encoding[Data Encoding and MediaTypes] in the official Infinispan documentation.
