camel-ironmq

This component has been donated to Apache Camel, and will be maintained there.

Ironmq component for Apaceh Camel to support integration with IronMQ an elastic and durable hosted message queue service.

The master branch targets IronMq v3 while v2 is supported using the v2 branch.

To run it requires a IronMQ account with projectId and token.

See examples below or the unit tests for how to use Camel and IronMQ together.

Status

Uri format:

ironmq://queue-name[?options]

URI options:

Name	Default value	Context	Description
client	null	Shared	Reference to a io.iron.ironmq.Client in the Registry.
projectId	null	Shared	IronMQ projectid
token	null	Shared	IronMQ token
ironMQCloud	https://mq-aws-us-east-1.iron.io	Shared	IronMq Cloud url. See IronIo documents for valid options
preserveHeaders	false	Shared	Should Camel headers be preserved. This will add the Camel headers to the Iron MQ message body as a json payload with a header list, and a message body. This is useful when Camel is both consumer and producer.
concurrentConsumers	1	Consumer	Number of concurrent consumers.
timeout	60	Consumer	After timeout (in seconds), item will be placed back onto the queue
maxMessagesPerPoll	1	Consumer	How many messages pr. poll.
batchDelete	false	Consumer	Should messages be deleted in one batch. This will limit the number of api requests since messages are deleted in one request, instead of one pr. exchange. If enabled care should be taken that the consumer is idempotent when processing exchanges.
wait	0	Consumer	Time in seconds to wait for a message to become available. This enables long polling. Default is 0 (does not wait), maximum is 30.
visibilityDelay	0	Producer	The item will not be available on the queue until this many seconds have passed. Default is 0 seconds.

The camel message body

Should be either a String or a array of Strings. In the latter case the batch of strings will be send to IronMq as one request, creating one message pr. element in the array on IronMq.

Message headers set by the IronMQ producer

Header	Type	Description
CamelIronMQOperation	String	If value set to 'CamelIronMQClearQueue' the queue is cleared of unconsumed messages.
CamelIronMQMessageId	String or io.iron.ironmq.Ids	The id of the IronMQ message as a String when sending a single message, or a Ids object when sending a single batch list of string messages.

Message headers set by the IronMQ consumer

Header	Type	Description
CamelIronMQMessageId	String	The id of the IronMQ message consumed.
CamelIronMQReservationId	String	The reservation of the IronMQ message.
CamelIronMQReservedCount	String	The number of times this message has been reserved.

Consumer example

• Consume 50 messages pr. poll from the queue 'testqueue', and save the messages to disk.

    from("ironmq:testqueue?projectId=myIronMQProjectid&token=myIronMQToken&maxMessagesPerPoll=50").to("file:somefolder)
  

Producer example

• Take the direct input and enqueue it on 'testqueue'.

    from("direct:start").to("ironmq:testqueue?projectId=myIronMQProjectid&token=myIronMQToken").
  

• Dequeue from activemq/jms and enqueue the message on Ironmq.

    from("activemq:foo).to("ironmq:testqueue?projectId=myIronMQProjectid&token=myIronMQToken").
