# == Class: swift::proxy::ratelimit
#
# Configure swift ratelimit.
#
# See Swift's ratelimit documentation for more detail about the values.
#
# === Parameters
#
# [*clock_accuracy*]
# (optional) The accuracy of swift proxy servers' clocks.
# 1000 is 1ms max difference. No rate should be higher than this.
# Defaults to $facts['os_service_default'].
#
# [*max_sleep_time_seconds*]
# (optional) Time before the app returns a 498 response.
# Defaults to $facts['os_service_default'].
#
# [*log_sleep_time_seconds*]
# (optional) if >0, enables logging of sleeps longer than the value.
# Defaults to $facts['os_service_default'].
#
# [*rate_buffer_seconds*]
# (optional) Time in second the rate counter can skip.
# Defaults to $facts['os_service_default'].
#
# [*account_ratelimit*]
# (optional) if >0, limits PUT and DELETE requests to containers
# Defaults to $facts['os_service_default'].
#
# [*container_ratelimit*]
# (optional) Hash of size(keys) and requests per seconds(values).
# Defaults to {}.
#
# [*container_listing_ratelimit*]
# (optional) Hash of size(keys) and requests per seconds(values).
# Defaults to {}.
