# Doing that is simpler and also protects you from shooting yourself in the foot,
# as certain workers can only be spawned just once.
#
# Each worker instance in the list defines the following fields:
# - `type` - the type of worker (`generic_worker`, etc.)
# - `instanceId` - a string that identifies the worker. The combination of (`type` + `instanceId`) represents the name of the worker and must be unique.
# - `port` - an HTTP port where the worker listens for requests (can be `0` for workers that don't do HTTP request processing)
# - `metrics_port` - an HTTP port where the worker exports Prometheus metrics
