Subject RE: Query regarding zip consumption using apache camel

You likely want to set some readLock parameter to your file consumer endpoints. The value
of that parameter depends a bit on your needs readLock=changed is slow but reliable, readLock=fileLock
is faster, but may not work reliably if you use a shared filesystem. There are other options,
so you should probably read the documentation for the file endpoint.

Best regards

Subject: RE: Query regarding zip consumption using apache camel


Thanks for the reply.

The problem is that there are 2 separate queue listening to the same folder one is for unzipping
the file and another one is for reading the pdf's and txt's As soon as I start copying the
zip file which is of 8-10 MB, camel starts unzipping the zip packet even before the completion
and the other queue starts reading the pdf's.

Queue 1 is something like this:-

from("file://{{rootOutputDirectory}} /incoming?	include=.*.zip&move=.done&moveFailed=.error&consumer.delay={{document.intake.delay}}")
		  .split(new ZipSplitter()).streaming()

Queue 2 is :-

<route id="document_management_file_processor">   
     <from uri="file://{{rootOutputDirectory}}/ incoming/?			  	include=.*\.pdf|.*\.xml&amp;sortBy=reverse:file:name&amp;move=.done&amp;moveFailed=.error&a
     <to uri="bean:documentIntakeFileProcessor"/>

I think your situation is a bit hard to guess unless you share your routing details.

In case, you directly consume files by trying to unmarshall them even if your file transfer
is complete.

If you use file component, you may need to look into exclude option to avoid consuming incomplete
transferred files.

Or you may need custom file processing strategy before unmarshalling files.

These are what i would suggest by just top of my head without knowing anymore details.
