feedback + missing karaf feature for sling with RDBDocumentStore?

[Ioan Eugen Stan <ie...@netdava.com>]

Hello,

I'm evaluating Sling to use as a CMS in our project. Since I'm planning
to use Karaf as the foundation I decidede to test that out.

I've managed to build and install a running Sling instance with oak tar
backend and played a bit with Composum.

Things worked fine so far, great job. e are planning to deploy Sling
with the RDBDocumentStore since we don't have Mongo experience and I
would not like to complicate the deployment. We also have established
procedures on how to backup and maintain a PostgreSQL database.

However I have noticed that the Karaf features.xml file is missing a
feature to deploy Sling with RDBDocumentStore backend.

Is this a simple omission or are there other reasons why this is not
provided? I'll be able to help build a feature for this case and
contribute it to Sling if it's just an omission. I may need some
guidance and code feedback.

Some other things I have noticed is that the features are not documented
and you don't know which features to install, without having experience
with the project.

Thanks,

As usual, contributions of such things are welcome, so Ioan if you
create such a feature for your own purposes feel free to suggest it as
a Sling sample contribution.

you should start with sling-launchpad-oak-tar when having no experience with 
Sling.

RDBDocumentStore requires different configurations per RDBMS/driver and it 
doesn't make sense to even add features for each supported system – you will 
have to adjust those configurations for production anyway (same for Oak/Tar 
and Oak/Mongo). A sample feature using RDBDocumentStore is planned though.

You should create your own sling-launchpad-oak-* feature based on sling-
launchpad-oak or even recreate that one if you are not sastisfied with its 
configurations.

The feature names should speak for themselves – in case of doubt look at the 
documentation of their bundles at 
http://sling.apache.org/documentation/bundles.html
