Puppet Class: swift::proxy::slo

Defined in:
manifests/proxy/slo.pp

Overview

Configure swift slo.

Examples

include swift::proxy::slo

Parameters

max_manifest_segments

(Optional) Max manifest segments. Defaults to $::os_service_default.

max_manifest_size

(Optional) Max manifest size. Defaults to $::os_service_default.

rate_limit_under_size

(Optional) Rate limiting applies only to segments smaller than this size. Defaults to $::os_service_default.

rate_limit_after_segment

(Optional) Start rate-limiting SLO segment serving after the Nth segment of a segmented object. Defaults to $::os_service_default.

rate_limit_segments_per_sec

(Optional) Once segment rate-limiting kicks in for an object, limit segments served to N per second. 0 means no rate-limiting. Defaults to $::os_service_default.

max_get_time

(Optional) Time limit on GET requests (seconds). Defaults to $::os_service_default.

concurrency

(Optional) Limit how many subrequests may be executed concurrently. Defaults to $::os_service_default.

delete_concurrency

(Optional) Limit how many delete subrequests may be executed concurrently. This may be used to separately tune validation and delete concurrency values. Defaults to $::os_service_default.

yield_frequency

(Optional) Frequency, in seconds, to yield whitespace ahed of the final response. Defaults to $::os_service_default.

allow_async_delete

(Optional) Allow clients to request the object-expirer handle the deletion of segments using query params like ‘?multipart-manifest=delete&async=on`. Defaults to $::os_service_default.

DEPRECATED PARAMETERS

min_segment_size

(Optional) minimal segment size Defaults to undef.
