@Experimental(value=SOURCE_SINK) public class AmqpIO extends java.lang.Object
It's also possible to use AMQP 1.0 protocol via Apache Qpid JMS connection factory and the Apache Beam JmsIO.
The AmqpIO AmqpIO.Read can bind a AMQP listener endpoint and receive messages. It can
also connect to a AMPQ broker (such as Apache Qpid or Apache ActiveMQ).
AmqpIO AmqpIO.Read returns an unbounded PCollection of Message
containing the received messages.
To configure a AMQP source, you have to provide a list of addresses where it will receive
messages. An address has the following form: [amqp[s]://][user[:password]@]domain[/[name]] where domain can be one of host | host:port | ip | ip:port | name. NB: the ~ character allows to bind a AMQP
listener instead of connecting to a remote broker. For instance amqp://~0.0.0.0:1234 will
bind a AMQP listener on any network interface on the 1234 port number.
The following example illustrates how to configure a AMQP source:
pipeline.apply(AmqpIO.read()
.withAddresses(Collections.singletonList("amqp://host:1234")))
AmqpIO provides a sink to send PCollection elements as messages.
As for the AmqpIO.Read, AmqpIO AmqpIO.Write requires a list of addresses where to
send messages. The following example illustrates how to configure the AmqpIO AmqpIO.Write:
pipeline
.apply(...) // provide PCollection<Message>
.apply(AmqpIO.write());
