Configuring mKahaDB persistence storage for ActiveMQ

Chandra Shekhar Pandey

In this post, I wanted to address how to configure mKahaDB persistence storage on ActiveMQ for better management and reducing disk usage. Default configured KahaDB persistence adapter works well when all the destinations (queues/topics) being managed by the broker have similar performance. However, an enterprise solution where several third parties are involved is never the case. There are multiple queues or topics and different consumers or listeners listening to these queues/topics. Some consumers might be slower than other consumers. This...

JBoss A-MQ on OpenShift Cheat Sheet

Abdellatif BOUCHAMA

We hear about Microservices a lot nowadays. Its implementation requires us to deal with new challenges. A key question that comes with using microservices is how to handle interactions in an asynchronous way. The answer to that is messaging . Among other things, messaging features the following: Loose coupling since it decouples client from services. Improved availability since the message broker buffers messages until the consumer is able to process them. Supports a variety of communication patterns including request/reply, notifications...

Messaging for IoT

== Abstract == Scale changes everything. What once was quite adequate for enterprise messaging can't scale to support "Internet of Things". We need new protocols, patterns and architectures to support this new world. This session will start with basic introduction to the concept of Internet of Things. Next it will discuss general technical challenges involved with the concept and explain why it is becoming mainstream now. Now we're ready to start talking about solutions. We will introduce some messaging patterns (like telemetry and command/control) and protocols (such as MQTT and AMQP) used in these scenarios. Finally we will see how Apache ActiveMQ is gearing up for this race. We will show tips for horizontal and vertical scaling of the broker, related projects that can help with deployments and what the future development road map looks like. == Speaker == Martyn Taylor is a senior software engineer at Red Hat, with over 7 years' experience working on cloud, middleware and messaging software. Martyn currently works on the Apache ActiveMQ suite of projects.

Persistence vs. Durability in Messaging. Do you know the difference?

Mary Cochran

Messaging is a critical aspect of integrating systems, and while there are many different messaging platforms and infrastructures, a common request is for "zero loss of messages." From there, the terms "Persistence" and "Durability" often get thrown around, but what do those two things really mean? Persistence At a basic level, persistence means that when failure occurs during message processing, the message will still be there (where you found it the first time) to process again once the failure is...

Scalable Microservices through Messaging

Bilgin Ibryam

Microservices are everywhere nowadays, and so is the idea of using service choreography (instead of service orchestration) for microservices interactions. In this article I describe how to set up service choreography using ActiveMQ virtual topics, which also enables scalable event based service interactions. Service Interaction Styles There are two main types of service interaction: synchronous and asynchronous . With synchronous interactions, the service consumer makes a request and blocks until the operation completes and a response is received. The HTTP...
