# Disaster recovery **(FREE SELF)**
2021-05-06 11:10:17 -04:00
2021-05-27 17:10:59 -04:00
This document describes a feature that allows you to disable some important but computationally
expensive parts of the application to relieve stress on the database during an ongoing downtime.

## `ci_queueing_disaster_recovery_disable_fair_scheduling`
2021-05-06 11:10:17 -04:00
2021-05-27 17:10:59 -04:00
This feature flag, if temporarily enabled, disables fair scheduling on shared runners.
This can help to reduce system resource usage on the `jobs/request` endpoint
by significantly reducing the computations being performed.
2021-05-06 11:10:17 -04:00
Side effects:
2021-05-27 17:10:59 -04:00
- In case of a large backlog of jobs, the jobs are processed in the order
they were put in the system, instead of balancing the jobs across many projects.

## `ci_queueing_disaster_recovery_disable_quota`
2021-12-22 04:13:51 -05:00
This feature flag, if temporarily enabled, disables enforcing CI/CD minutes quota
2021-07-01 11:07:40 -04:00
on shared runners. This can help to reduce system resource usage on the
`jobs/request` endpoint by significantly reducing the computations being
performed.
Side effects:
2021-05-06 11:10:17 -04:00
- Projects which are out of quota will be run. This affects
2021-05-27 17:10:59 -04:00
only jobs created during the last hour, as prior jobs are canceled
by a periodic background worker (`StuckCiJobsWorker`).
