Hello List!
I managed to find the answer to my own question.
The pipeline reads the entire file into memory by default. With the
<map:parameter name="outputBufferSize" value="8192"/>
entry, you can set the buffer size, so it doesn't fill up the entire heapspace. It is also advised to set the pipeline type to noncaching that so the entire cache isn't filled with the large file.
Here is an example:
<map:pipeline type="noncaching"> <map:parameter name="outputBufferSize" value="8192"/> <map:match pattern="**.zip">
<map:read src="{1}.zip" mime-type="application/octet-stream"/> </map:match>
</map:pipeline>
Thank you, Michael Wirz
Hello List,
when trying to serve big zip files through cocoon we encounter OutOfMemoryErrors.
Our setup is as follows:
(default) reader definition:
<map:readers default="resource">
<map:reader logger="sitemap.reader.resource" name="resource" pool-max="32" src="org.apache.cocoon.reading.ResourceReader"/>
</map:readers>
pipeline matching the request: <map:match pattern="*/downloads/special/*.zip"> <map:read src="downloads/{1}/{2}.zip" mime-type="application/zip"/> </map:match>
Does anyone know whether there's a filesize limitation? Any work arounds other than increasing heap memory? Is there a way to stream the binary (i.e. a StreamingReader or similar)?
Thanks in advance for help, Michael
