Hi, Anyone thinking about hooking up CDO to to Hadoop system? In my
domain, it would make a lot of sense to fill a hadoop system, which can
be presented nicely in objects to RCP clients. Some of the Hadoop
tooling, looks promising for this.

Hi Eike,
Well, I probably know as much as you do, which is the Hadoop keynote
this morning :-) When the ecosystem was discussed, there was a few
addons which caught my interest:

http://hive.apache.org/

Hi Markus,
Transactions with ACID properties are a fundamental aspect of CDO. Most NoSQL databases do not fully support them.
