Urgent - Reprocess/Consume the same file again - Camel Route

[Prithiv <sa...@ericsson.com>]

Hi,
Following is a scenario, Please suggest. 
I have a file say A.txt in input folder.
The camel route kicks in, puts in the location of file(filepath/filename) in
a message queue and subsequent process picks up the file, processes it and
the last process moves it to a DONE directory.
Now the requirement is to reprocess the same file A.txt again
(filesize,timestamp,etc being the same) if it is placed in the input folder.
Idempotent = false doesn't work in my scenario, because i see multiple
messages in queue getting created during the route flow.
Is there a way or substitute for alwaysConsume ? or Setting the LRUCacheSize
to 1 ?

Thanks in advance & Appreciate your help

You can use a custom idempotent repo and then remove the key when you
want to re-prorcess the file again. Such as when you have moved it to
the DONE directory.

Or you can use a custom filter, and then return false, while you are
still processing the file, eg it has not been moved to DONE folder.

Hi,
I'm having the same problem.  Looks like Camel caches 1000 file names.  I'm
also waiting for a solution/workaround for this.

Thanks,
Ram
