> Its still common to transfer data using files and using a marker file when the data is ready.
> We should have a feature on the file consumer, so it can be used to scan for marker files, and then use the real file as the message body.
> And then when its done it can delete/move both files.
> The problem is how to define an easy way of correlating the marker file to the real file. We can use an Expression for that.
> For example maybe something like, (use better option names)
> {{realFile=${file:name.noext}.csv&include=.*.ready}}
> Then Camel will react when there is a .ready file in the folder. And evaluate the expression and see if a file with that result exists.
> When it's done the marker file should be deleted, and the real file should be moved using the existing options for that.
