In python apache beam, is it possible to write elements in a specific order?
While this isn't part of the base distribution, this is something you could implement by processing these elements and sorting them as part of a global window before writing out to a file, with the following caveats:

The entire contents of the window would need to fit in memory, or you would need to chunk up the file into smaller global windows.
If you are doing the second option, you'd need to have a strategy for writing the smaller windows in order to the file.
I'm using beam to process time series data over overlapping windows. At the end of my pipeline I am writing each element to a file. Each element represents a csv row and one of the fields is a timestamp of the associated window. I would like to write the elements in order of that timestamp. Is there a way to do this using the python beam library?
