Subject Re: Delta store
Date Thu, 02 Jan 2014 09:24:53 GMT
Hi Pablo,
Ironically I started work on this feature over the weekend as it is next on
my list of must haves for my own personal project which also uses MongoDB.
I've had to upgrade the MongoDB driver and add in the morphia plugin for
modelling the delta store which hopefully I'll be able to continue working
on over the weekend.  My time is limited and so if you think you'll be able
to finish before me let me know and I'll try and help with any knowledge
I've gained around mongoDB.  It looks like getting the delta store finished
is going to be fiddly work from what I've seen so far, I started by
modelling the store on the memory version, but the first problem I've found
is that the '.' in mongoDB is a reserved character so I'm going to have to
start modelling the store using a mongoDB specific implementation.

If it helps I've uploaded my current work
just keep in mind is very much just the beginning.
