Python - job.handler()

Job handlers are the code that is run when a job request is submitted. These handlers should be written in a separate file to your services.

from nitric.resources import job



analyze = job("analyze")



@analyze(cpus=1, memory=2048, gpus=0)

def do_analyze(data):

  # Run batch job

  pass
