Tobias Wunden commented on MH-9154:
-----------------------------------
Ruben, when dealing with large files it may make sense to keep using the
streams you get at the REST endpoint level (you usually get an InputStream, not
a File object) and it would not be efficient to store this file locally, then
call File.length() and then move the file on to e. g. the backend store such as
the working file repository or the archive element store. Instead, we can deal
with the fact that it's a stream and keep counting the bytes as they flow by.
With regards to being able to send the files back to the client, again your
method works if you have access to the file wich is not the case with the
Episode service's elment store. That service is dealing with streams to enable
different implementations that may be remote, in which case you want to be
dealing with streams rather than files.
Regarding your EDIT, in this case the service is doing everything in the
correct way, it's asking the inspection service to determine the size.
Unfortunately, there are two bugs, one in the inspection service (it is not
setting the size even though it has it) and one in the mediapackage (the "size"
field is never serialized to JAXB entities) that prevent these things from
working.
