Design ideas for file merging

[jjarkko]

Hello,
Let's say there's directory where multiple files might appear ( /in/ ). I know there's going to be at least one file at 12:00 every day, but there might be any number of files between 1 to 10.

Now, if there'are more than one file I need to concatenate all the files to a single file which is then later sent forward (written to an other directory).

Any ideas how to implement this?

Some processing might be needed for each individual file and maybe for the concatenated file also.

Did everybody understood what I'm after? ;)

br,
Jarkko

I implemented this by modifying the existing Aggregator a bit.

How did you address the lack of "statefulness" in the aggregator? Or does it not matter in your use case?
