#include <userver/congestion_control/component.hpp>

Detailed Description

Component to limit too active requests, also known as CC.

Dynamic config

Static options:

Name Description Default value
fake-mode if set, an actual throttling is skipped, but FSM is still working and producing informational logs false
min-cpu force fake-mode if the current cpu number is less than the specified value 1
only-rtc if set to true and hostinfo::IsInRtc() returns false then forces the fake-mode true
status-code HTTP status code for ratelimited responses 429

Static configuration example:

# yaml
congestion-control:
fake-mode: true
min-cpu: 2
only-rtc: false
# Uncomment if you want to change status code for ratelimited responses
# status-code: 503
# Common component options
load-enabled: true
