Apache Artemis thoughts

Intro

This file is meant to collect all my findings about the Apache ActiveMQ Artemis message queueing system. Although the framework documentation seems to be huge, it does not cover many situations anyone can get into while trying to adopt the technology.

I like to use Groovy along with the Core API.

Static discovery connection URL for multiple servers

Just separate the URLs with a hashmark:

tcp://10.0.0.2:61616#tcp://10.0.0.3:61616

This will get handy when you can't or don't want to use the UDP discovery and/or the JMS API. Usage with the Core API:

def locator = ActiveMQClient.createServerLocator('tcp://10.0.0.2:61616#tcp://10.0.0.3:61616')

But you may want to combine this with high availability setting (without it, the offline servers would be skipped only upon the initial connection, not in case of failure):

tcp://10.0.0.2:61616?ha=true#tcp://10.0.0.3:61616?ha=true
