Mule, Esper CEP and non-events

3

I was reading John D’Emic’s brilliant post Twitter Complex Event Processing (CEP) with Esper and Drools and got truly inspired. After playing around with the combination of and I was amazed how good they suit each other. Letting do the hard work of shuffling data and intelligent routing while Esper analyzing events on a overall level. It gave me kind of a opportunity to be stateful in a stateless environment. For those who aren’t familiar with Esper, it is what is called a Complex Event Processing engine that allows you to create queries and assertions on streams of events in real-time.

Introduction

The architecture of is driven by the principles of Industrial Best Practice as outlined in the well-known Enterprise Integration Patterns which have identified the most common building blocks for every integration problem. These building blocks are what make up Mule Flows, the executable units inside Mule Applications. No matter what the problem, wiring them together into an integration solution is extremely easy and by exploiting the power of Mule’s native support for the Drools Rules Engine, the Integration Developer has a very powerful set of tools to tackle even the most complex of integration problems with the greatest of ease. With this post I hope to be able to demonstrate  this to you!

Complex event processing engines are a natural fit for event driven platforms like . Native   support has been available in since version 3.2 by way of the Drools Module.  The Esper Module now offers an alternate way to leverage CEP in your integration applications.   Esper is a robust, performant, open source, complex event processing engine.  Let’s take a look at how to use with Mule and then see how it compares to ’ CEP support.

Get a sneak peek at Mule 3.2

3.2 is right around the corner and it is shaping up as the best release ever.

Some highlights include:

  • High availability for mission critical environments
  • A to gain deep visibility into business events for root cause analysis and compliance
  • integration for business rules and complex event processing

In part 1 of this post, I gave an overview of , , and and the way they compliment an integration platform such as . Now let’s take a look at what has to offer for integrating with some of these tools.

One of the more common usages of is as the integration piece of a larger SOA architecture. Mule has traditionally never attempted to offer a complete SOA suite/stack of products as some of its larger competitors do, but has rather focused on the thing it does best, which is integration. Other aspects of an SOA architecture (messaging backbone, data storage, governance, etc.) are generally provided by other best-of-breed solutions for those areas, and Mule allows you to integrate with as many different options as possible.
