# Background jobs that must be run async due to long time to completion
# NOTE: due to an issue with Celery + SQLAlchemy 
# (https://github.com/celery/celery/issues/7007#issuecomment-1740139367)
# we must use the threads pool instead of the default prefork pool for now
# in order to avoid intermittent errors like:
# `billiard.exceptions.WorkerLostError: Worker exited prematurely: signal 11 (SIGSEGV)`. 
#
# This means workers will not be able take advantage of multiple CPU cores 
# on a system, but this should be okay for now since all our celery tasks are
# relatively compute-light (e.g. they tend to just make a bunch of requests to 
# Vespa / Postgres)
