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 Christophe,

I myself have no experience with Hadoop, yet. I notice that they have a bunch of sub projects. Can you point me to some more specific pages that I can read to make a sense out of it?

Do you have plans to implement an integration between CDO and Hadoop?

Cheers
/Eike

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/

There is some work in progress on putting EMF into Hadoops HBase kv-stores. We basically fragment a model automatically into multiple resources and map resources and their urls to keys and values. Clients can control fragmentation with meta-model annotations.

Hi Markus,

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