# Number of worker processes to spawn.
# Set to 0 to run everything in a single process without clustering.
num_workers: 0

# Number of workers to start in parallel after the first worker.
# The first worker is always started independently. After it has completed
# its start-up, this number controls the number of workers to start in
# parallel until `num_workers` have been started. Note that setting this
# number to a too high a value might lead to high resource consumption
# (especially of CPU) during the start-up process.
startup_concurrency: 2

# Number of milliseconds to wait for a heartbeat from worker before killing
# and restarting it
worker_heartbeat_timeout: 7500
