Claus Ibsen updated CAMEL-3163:
-------------------------------

    Description: 
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.
