Brett Porter commented on MRM-1327:
-----------------------------------

If JCR is selected, we also need to chose it's persistence mechanism. If that 
happens to be a lightweight internal database (like H2), note that it might 
conflict/double up with the default Derby still used for redback. It also needs 
to be easy to reconfigure as it was before.

> implement alternative or improve repository metadata storage

> The biggest thing to look at is metadata-repository-file. I threw this 
> together with property files quickly and there's no optimisation or even 
> exception handling. We need to look at the right way to approach this - a 
> more robust implementation of a file system store (properties or xml) is 
> definitely workable, but would need to be combined with something like a 
> Lucene index (as in Archiva 0.9) to make some of the operations fast enough. 
> What I would like to look at instead is using JCR (with file system 
> persistence - not a database!) to see how well it reacts to a lot of 
> operations. As you can tell from the docs, the storage is tailored to living 
> in a hierarchical content repository in whatever form that takes, and the 
> storage is isolated behind an API.
