Consume ActiveMQ JMS MapMessages from Delphi

One outstanding feature of the popular Apache ActiveMQ message broker is its rich message conversion capability, which allows cross-platform/cross-language exchange by serialization of JMS object and map messages to XML or JSON.

RabbitMQ Hits One Million Messages Per Second on Google Compute Engine

In this blog post of 2014, Jerry Kuch describes a performance study of RabbitMQ on Google Compute Engine. It demonstrated the ability to receive and deliver more than one million messages per second (a sustained combined ingress/egress of over two million messages per second).

At this high rate of combined ingress (1,345,531 messages per second) and egress (1,413,840 messages per second), RabbitMQ was keeping up with load and that only 2,343 messages are temporarily accumulated in its queues awaiting delivery.

Daraja Framework RESTful extension 2.1 released

Daraja Framework is a free open source library for Object Pascal, based on the stand-alone HTTP server in Internet Direct (Indy).

In the past, the separate “experimental” RESTful extension library only compiled with Delphi, as it used anonymous methods.

With version 2.0 / 2.1, the RESTful extension library now also compiles with Free Pascal, where it uses procedural types instead of anonymous methods.
