Use Sensors with Inotify

[dridk]

Hi,

Actually, if you want to trigger a job when a new file appear, you must create a sensors which loop over files every N seconds.

It would be awesome to have a Sensors triggered by inotify . When a new file is created, the file system can send a message ( IN_CREATE ) which can be catch by dagster to start the job. For instance :

@sensors(job=my_job,  watch="/myfolder",  event="IN_CREATE")
def my_sensors(context):
     yield RunRequest(context.inotify.file)
