Subject Re: S3 MultiPart upload for InputStream
Date Wed, 29 Mar 2017 16:56:34 GMT
Hi Artur,
I don't think that the implementation will load the whole file in
memory, looking at CAMEL-7991[1] that introduced multipart support the
reasoning behind it was to reduce the memory usage.
That being said if you have the need for passing InputStream instead,
could you consider contributing support for that, see Contributing at

thanks :)
