Puppet Class: swift::proxy::ratelimit

Defined in:
manifests/proxy/ratelimit.pp

Overview

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.

max_sleep_time_seconds

(optional) Time before the app returns a 498 response. Defaults to $facts.

log_sleep_time_seconds

(optional) if >0, enables logging of sleeps longer than the value. Defaults to $facts.

rate_buffer_seconds

(optional) Time in second the rate counter can skip. Defaults to $facts.

account_ratelimit

(optional) if >0, limits PUT and DELETE requests to containers Defaults to $facts.

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 {}.
