[FLOW3-general] MongoDB support

[Georg Grossberger]

Hi Arnaud

I invested a couple hours in that recently. My approach contains three 
packages: "Doctrine.MongoDB", "Doctrine.ODM.MongoDB" and "TYPO3.MongoDB" 
- (do you guys mind the TYPO3 prefix? I can change it if you want to).

There are two difficulties ahead:

1) Get the whole thing to work (of course). Since those new Doctrine 
packages are all about "Documents" instead of "Entities", a lot of 
things need to be adjusted and implemented differently than in the 
FLOW3\Persistence\Doctrine sub-package. e.g.: so far I found no way to 
satisfy Repositories, extending the Flow3 Doctrine repository. The 
common one is not a big issue as it basically passes everything to the 
persistence manager.

2) How to define documents? I thougt about this: Aggregate roots are 
always documents, so are entities which are referenced by more than one 
other entity-type. Non-root entity-types, that are only referenced by 
one (other) entity-type (1:n, 1:1, and no other relations) are Embedded 
Documents.

As I said, so far it's more like playing around with some code, than an 
actual project, so please be a little patient :)

chrz,
Georg

We are also in good contact with Derick Rethans who works at 10gen and said that they'd be glad helping anyone getting started with developing MongoDB support for FLOW3.
