> Hello.
> There is a problem with the processing of flow-files in python processors,
> which are connected using the setting
> nifi.python.processor.dir=./minifi-python/
> If you need to split one file into several, then you have to create new files
> in the Python processor and be sure to transfer the original one to
> REL_FAILURE.
> Otherwise, if I do not pass the original file to REL_FAILURE, then the
> processing result is rolled back and nothing happens
> It seems to me that it is necessary to make it possible for Python processors
> to add various relations, and not just REL_FAILURE REL_SUCCESS.
> Or add an additional possible relationship REL_ORIGIN to which you can pass
> the original file
> That. if you look at the metrics for these processors, you see
> TransferredToFaillure > 0, although the processors processed without errors
> Another additional possibility is to add the session.remove (flowfile )
> method (as it is done for example in the processor ExecuteSQL). Then it will
> be possible to exclude incoming files from further processing
