--------------------------------------
Summary: StreamCache does not work correctly with MarshalProcessor
and pretty much all DataFormats
Key: CAMEL-9274
URL: https://issues.apache.org/jira/browse/CAMEL-9274
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.16.0
Reporter: Aaron Whiteside
Priority: Critical
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.
