Atomix Map

Since Camel 2.20

Both producer and consumer are supported

The camel Atomix-Map component allows you to work with Atomix’s Distributed Map collection.

Maven users will need to add the following dependency to their pom.xml for this component:

    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-atomix</artifactId>
        <version>${camel-version}</version>
    </dependency>

URI format

    atomix-map:mapName

Options

The Atomix Map component supports 18 options, which are listed below.

Name Description Default Type

atomix (common)

The Atomix instance to use

Atomix

configuration (common)

The shared component configuration

AtomixMapConfiguration

configurationUri (common)

The path to the AtomixClient configuration

String

defaultAction (common)

The default action. The value can be one of: PUT, PUT_IF_ABSENT, GET, CLEAR, SIZE, CONTAINS_KEY, CONTAINS_VALUE, IS_EMPTY, ENTRY_SET, REMOVE, REPLACE, VALUES

PUT

Action

key (common)

The key to use if none is set in the header or to listen for events for a specific key.

Object

nodes (common)

The nodes the AtomixClient should connect to

List

resultHeader (common)

The header that wil carry the result.

String

transportClassName (common)

The class name (fqn) of the Atomix transport

io.atomix.catalyst.transport.netty.NettyTransport

String

ttl (common)

The resource ttl.

long

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

basicPropertyBinding (advanced)

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

false

boolean

defaultResourceConfig (advanced)

The cluster wide default resource configuration.

Properties

defaultResourceOptions (advanced)

The local default resource options.

Properties

ephemeral (advanced)

Sets if the local member should join groups as PersistentMember or not. If set to ephemeral the local member will receive an auto generated ID thus the local one is ignored.

false

boolean

readConsistency (advanced)

The read consistency level. The value can be one of: ATOMIC, ATOMIC_LEASE, SEQUENTIAL, LOCAL

ReadConsistency

resourceConfigs (advanced)

Cluster wide resources configuration.

Map

resourceOptions (advanced)

Local resources configurations

Map

The Atomix Map endpoint is configured using URI syntax:

atomix-map:resourceName

with the following path and query parameters:

Path Parameters (1 parameters):

String

Query Parameters (20 parameters):

Name Description Default Type

atomix (common)

The key to use if none is set in the header or to listen for events for a specific key.

Object

nodes (common)

The address of the nodes composing the cluster.

String

resultHeader (common)

String

transportClassName (common)

The class name (fqn) of the Atomix transport

io.atomix.catalyst.transport.netty.NettyTransport

String

ttl (common)

The resource ttl.

long

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. The value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

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.

Configuring the component to connect to an Atomix cluster

The nodes of the Atomix cluster you want to join can be se at Endpoint or component level (recommended), below some examples:

  • Endpoint:

    <beans xmlns="...">
    <camelContext xmlns="http://camel.apache.org/schema/spring">
        <from uri="direct:start"/>
            <to uri="atomix-map:myMap?nodes=node-1.atomix.cluster:8700,node-2.atomix.cluster:8700"/>
        </route>
    </camelContext>
</beans>

  • Component:

    <beans xmlns="...">
    <bean id="atomix-map" class="org.apache.camel.component.atomix.client.map.AtomixMapComponent">
        <property name="nodes" value="nodes=node-1.atomix.cluster:8700,node-2.atomix.cluster:8700"/>
    </bean>

    <camelContext xmlns="http://camel.apache.org/schema/spring">
        <from uri="direct:start"/>
            <to uri="atomix-map:myMap"/>
        </route>
    </camelContext>
</beans>

Usage examples:

  • PUT an element with TTL of 1 second:

    FluentProducerTemplate.on(context)
    .withHeader(AtomixClientConstants.RESOURCE_ACTION, AtomixMap.Action.PUT)
    .withHeader(AtomixClientConstants.RESOURCE_KEY, key)
    .withHeader(AtomixClientConstants.RESOURCE_TTL, "1s")
    .withBody(val)
    .to("direct:start")
    .send();

Spring Boot Auto-Configuration

When using atomix 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-atomix-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
