------------------------------------
Yeah lets see how invasive the changes are and whether that would be safe to
backport to 2.16.x
> StreamCache does not work correctly with MarshalProcessor and pretty much all
> DataFormats

> StreamCache does not work correctly with MarshalProcessor and pretty much all
> DataFormats
> # Documentation states that stream caching can be turned on, on a per route
> basis. The places were we actually try and utilize stream caching only checks
> if the global option is turned on (MarshalProcessor + PGPKeyAccessDataFormat,
> I can't find any other meaningful attempts to use stream caching anywhere
> else) not the per route setting.
> # Secondly, if we ignore the first problem, only one data formatter tries to
> use stream caching for unmarshaling: PGPKeyAccessDataFormat. If you try and
> unzip a large zip file it's contents will be decompressed into memory. The
> same goes for any other large data formatter conversion (unmarshaling, only).
> Attached is a patch that corrects the first problem and part of the second
> problem (ZipFileDataFormat, ZipDataFormat and PGPKeyAccessDataFormat).
> A separate issue should probably be opened to fix all the remaining
> DataFormat implementation to support Stream Caching.
