parallelization of events notification in case of file creation - file

Question

I am using "Inotify" to logs event when a file or folder is created in a directory ( tmp here) . The example here does the job in as serial process. Meaning, All file creation are treated one after the other, in a sequential way.
import logging
import inotify.adapters
_DEFAULT_LOG_FORMAT = '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
_LOGGER = logging.getLogger(__name__)
def _configure_logging():
_LOGGER.setLevel(logging.DEBUG)
ch = logging.StreamHandler()
formatter = logging.Formatter(_DEFAULT_LOG_FORMAT)
ch.setFormatter(formatter)
_LOGGER.addHandler(ch)
def _main():
i = inotify.adapters.Inotify()
i.add_watch(b'/tmp')
try:
for event in i.event_gen():
if event is not None:
(header, type_names, watch_path, filename) = event
_LOGGER.info("WD=(%d) MASK=(%d) COOKIE=(%d) LEN=(%d) MASK->NAMES=%s "
"WATCH-PATH=[%s] FILENAME=[%s]",
header.wd, header.mask, header.cookie, header.len, type_names,
watch_path.decode('utf-8'), filename.decode('utf-8'))
finally:
i.remove_watch(b'/tmp')
if __name__ == '__main__':
_configure_logging()
_main()
I would like to introduce parallelization of the events notification in case of several files are uploaded by importing threading, should I add a threading as loop ?
Second concern, I am not sure where it would make sens to put the thread function.

The below scripts handles multiples events in case of multiples sessions. So in my case, this is enough. I Added the multiprocessing option instead of threading. I found multiprocessing faster than threading.
import logging
import threading
import inotify.adapters
import multiprocessing
_DEFAULT_LOG_FORMAT = '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
_LOGGER = logging.getLogger(__name__)
def _configure_logging():
_LOGGER.setLevel(logging.DEBUG)
ch = logging.StreamHandler()
formatter = logging.Formatter(_DEFAULT_LOG_FORMAT)
ch.setFormatter(formatter)
_LOGGER.addHandler(ch)
def PopUpMessage (event):
if event is not None:
(header, type_names, watch_path, filename) = event
_LOGGER.info("WD=(%d) MASK=(%d) COOKIE=(%d) LEN=(%d) MASK->NAMES=%s "
"WATCH-PATH=[%s] FILENAME=[%s]",
header.wd, header.mask, header.cookie, header.len, type_names,
watch_path.decode('utf-8'), filename.decode('utf-8'))
def My_main(count):
i = inotify.adapters.Inotify()
DirWatcher=i.add_watch(b'/PARA')
try:
while True:
for event in i.event_gen():
m = multiprocessing.Process(target=PopUpMessage, args=(event,))
m.start()
finally:
i.remove_watch(b'/PARA')
if __name__ == '__main__':
_configure_logging()
N = multiprocessing.Process(target=My_main)
N.start()
