There are loads of use cases which require “all or nothing” processing. And there are a bunch of different strategies for accomplishing said result. Luckily for me, they’ve already been covered many times in tons of different blogs/books/articles. So for this post I’m just going to concentrate on a few of the strategies, and more specifically, how to do them with Apache Camel.
When out and about, I often get the question: “How do I setup HA (high availability) with Red Hat’s JBoss Fuse?”. People ask this question and they expect a simple, straightforward answer. And why shouldn’t they? The question is simple enough right? I could ask the same question about something like Tomcat and get a well documented answer involving little more than a loadbalancer. Unfortunately, the answer for Fuse is a bit more involved and usually starts with the annoying response of “it depends”.
In many environments, it is common to ingest data as a batch process. This is usually accomplished by polling a directory (or FTP server) for files. The issue is that polling for files is a one-way communication. So if you get a file that you can’t parse (or one that is invalid for any other reason), you have no way of communicating that back to the original sender. How do you handle the error? You likely can’t just drop the data on the floor. That really only leaves one option and that is to correct the data and re-ingest it.
This is a follow-on to the excellent blog post that my colleague Christian Posta wrote on doing CI/CD with Fuse Fabric. In particular, this post will extend upon his write-up by showing how to migrate Fabric8 profiles and Maven artifacts into environments which are disconnected from the development environment.
This guide demonstrates step-by-step how to connect a FeedHenry Hello World application to a JBoss Fuse REST quickstart backend running on Red Hat’s OpenShift Online.
This guide demonstrates step-by-step how to create a Fuse cluster and deploy one of the quickstart applications using Red Hat’s OpenShift Online infrastructure.
This guide demonstrates step-by-step how to create a sample Camel project in JBoss Developer Studio (JBDS) using the Maven archetypes that come out of the box. Specifically, we’ll be creating a Spring based file poller project. We’ll then deploy the project to a JBoss Fuse server and verify that it is running properly.
