Subject [jira] [Commented] (AMQ-5471) Configuration server for Network of Brokers
Date Tue, 02 Dec 2014 22:25:13 GMT


Tim Bain commented on AMQ-5471:

Maybe you need to rewrite the description, then.

Your current text focuses on how distributed clients can access a central server to retrieve
content.  Apache, Git, Maven repos, etc., all already meet that need (and, frankly, should
be how you implement distribution of config files, so you don't have to worry about security
features, etc.).  For that part of it, yes, I think this is innovation in the wheel industry.
 Keep in mind too that "simpler" often turns out to mean "half-implemented solution that only
meets my particular needs"; reusing an existing COTS product is in fact probably simpler than
maintaining your own custom implementation of a web server, and it'll hit all the use cases
instead of just the ones you feel like spending time on.

If your real innovation here is an easy way to dynamically generate the config files for a
given broker based on input you collect, or a visual editor for config files, or any of a
number of improvements to the process of actually generating the config files, then go for
it.  But since there's no mention whatsoever of any of that in your initial description, you
probably should refocus the description to focus on those aspects.  And I still think that
however you generate the config files, you should serve them up via a COTS product such as

> Brokers use the xbean configuration to start which is usually found in ./conf other other
places on the local disk. In a NOB topology however it is hard to distribute the configuration
files and maintain them across brokers especially with a growing or elasticly changing number
of brokers.
> ActiveMQ already supports reading the xbean configuration from an http;// URL, so it
would be very helpful to have a rest service that manages the configuration for all the brokers.

> I started such a service on [github|] but plan
to contribute it to ASF once it's in a decent shape, in a couple of weeks or so.
> The service uses the local file system and appropriate conventions to store all the relevant
broker configuration resources (e.g. could be generated with ./bin/activemq create <instance>
minus certificates probably). I plan to enhance it later to support a git repository for the
configuration, so that it's versioned, so that an operator could roll out a new NOB topology,
or roll back to the previous configuration.
> Feedback appreciated.
