RabbitMQ-Receiver is a library that allows the user to read data with Apache Spark Streaming from RabbitMQ.
This code demonstrates how to read data from a RabbitMQ stream using Spark's RabbitMQ connector. The SparkConf object is used to set the configuration parameters for the connection details, the exchange, and the queue. The StreamingContext is used to create the Spark streaming context with a batch interval of 1 second.
The RabbitMQUtils.createStream() function is used to create a DStream of data from RabbitMQ with the given configuration. It takes in various arguments such as uri for the connection details, QueueDescription for setting up the queue parameters, ExchangeDescription for setting up the exchange parameters, and the routing_key for the desired binding of the queue to the exchange.
Finally, the print() method is called on the stream to display the received data, and the start() method is called on the StreamingContext to start the streaming process, followed by awaitTermination() to wait for the process to terminate.
