Habari Client libraries release 2018.10

Habarisoft released the 2018.10 version of its Object Pascal STOMP client libraries for application integration with open source message brokers (Apache ActiveMQ, Artemis, OpenMQ and RabbitMQ).

New in this release

  • new simple API, based on interfaces MQContext, MQProducer and MQConsumer (the old API still may be used)

Example:

procedure TNewApiTests.TestSendMessage;
var
  Factory: IConnectionFactory;
  Context: IMQContext;
  Destination: IQueue;
  Producer: IMQProducer;
  Consumer: IMQConsumer;
  TextMessage: ITextMessage;
begin
  Factory := TBTConnectionFactory.Create;

  Context := Factory.CreateContext;
  try
    Destination := Context.CreateQueue('example_queue');

    Producer := Context.CreateProducer;
    Producer.Send(Destination, 'Hello World');

    Consumer := Context.CreateConsumer(Destination);
    TextMessage := Consumer.Receive(2500) as ITextMessage;

    CheckEquals('Hello World', TextMessage.Text);
  finally
    Context.Close;
  end;
end;
  • a new connection URL parameter “message.subscription_check=false” allows to subscribe from multiple destinations with a single consumer, by disabling a client-side check subscription id
  • removed support for asynchronous message receive

Understanding When to use RabbitMQ or Apache Kafka

This article presents and compares the origins, architectures, and use cases of Apache Kafka, which is designed for high volume publish-subscribe messages and streams, and RabbitMQ, a general purpose message broker.

RabbitMQ is a “traditional” message broker that implements a variety of messaging protocols. (…) Apache Kafka is developed in Scala and started out at LinkedIn.

Starting with this release, the library requires Delphi 2009 or Free Pascal 3.0.2 (or newer), it is not compatible with non-Unicode versions of Delphi. The internal version numbers of all client libraries in the 2017.04 release is 5.0.0.
