changed data is not reread
DX avoids re-execution of a module by saving its output in cache, and using the cache if the module's inputs have not changed. That is why it is not re-reading your file.
I think you can turn off the cache for a particular module. However, this may mean DX re-reads the file every time the pipeline updates.
You could have your file change the name of the file each time it is written: stuff1.dat, stuff2.dat, ... , then send the new file name down your pipe each time one is ready.
Yet another approach is possible if the DX input module you use has other parameters that make little difference. Perhaps some option that is not actually used for your type of data. If so, have your application send a new version of this parameter after the data file has changed to trick DX into re-reading the file.
