[cdo] streaming large data? [message #621801] Wed, 15 September 2010 20:48

Hi guys!

I currently do a little POC for guys, I convinced that CDO's is the best
solution for their needs ;-)

My usecase is the following:

A client-server application:
The clients are RCPs, the server is running in an OSGI runtime.
The server holds files that get derlivered to it by various channels
(ftp, stick, etc.). The server maintains an index of those files and
processes/parses them. The server shall deliver the files (raw or in
parsed form) if clients request it. The files are huge (up to 1GB and
more) and shall not get into a db.
The clients shall be informed of new files on the server (read only) and
shall be able to request them.

I intend to implement the shared index with cdo.
I currently don't see a way to stream those larges files with cdo
(imagined a 2nd repo with a custom file-store), since cdo is no able to
stream (net4j on the other hand is) large data:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=284307

Do I miss something? Any progress on this? Any better idea?

I currently think at doing a minimalistic alternative and serving those
files with a web-server. An interesting one would also be to provide
remote osgi services. But this gets slightly off-topic.

Thanks for your ideas and inputs!

Cheers
André
