Heap size requirement regarding upload large files using MTOM

Hello all,

I am going to implement a CXF web service for client to upload a large
binary file (say 30MB), with MTOM enabled.

The web service may be concurrently called by a number of users, peak may be
50 people together.

I would like to ask will CXF MTOM have all the receiving data in memory, for
example, if 50 people is using the web service to upload the file, I may
need additional 30MB x 50 = 1.5GB heap space, or while data is uploading ,
the data will be streamed to a temporarily file? 

Thanks.
