[backend_ratelimit]
# The rate of requests to each device is limited by an overall per-device rate
# limit that is applied to all requests to the device and/or a
# per-method-per-device rate limit that is applied to requests of that method
# to the device. If either of these rates would be exceeded the server will
# return 529 responses and emit a 'backend.ratelimit' statsd metric without
# logging.

# Set the maximum overall rate of requests per device per second per worker for
# all request methods. The default value of zero causes no per-device
# rate-limiting to be applied other than that configured for specific request
# methods.
# requests_per_device_per_second = 0.0

# Set maximum rate of requests per device per second per worker for individual
# request methods. The default value of zero causes no per-method
# rate-limiting to be applied. Note: the aggregate rate of requests for all
# methods is still limited by requests_per_device_per_second even if a higher
# per method rate is configured.
