[General] Any experience with large attachment in an SOA platform ?

[cdeneux]

I think that it's possible to porcess large file using stream capabilities. It seems to me that all files are processed as stream. So if we use a specific stream implemenatation that flushes the file on disk if its size is upper that a configurable value, the large files will be correctly supported without introducing other things.

On other optimisation point is: how to avoid several flushs of the same large file if the attachment is processed several times by different components on the same PEtALS instance ?
