What does this MR do?
Enabling the Auto Cancel Redundant Pipelines may cause high CPU load on the database and may impact Sidekiq. This MR adds a note about this and possible workarounds and how to disable this setting on the instance-wide if needed.
We had several support tickets and had some emergency calls due to this setting. It would be good to note it so that both customers and support can identify the cause quickly if it is caused by this setting.

Author's checklist
-
Optional. Consider taking the GitLab Technical Writing Fundamentals course. -
Follow the: -
If you're adding a new page, add the product availability details under the H1 topic title. -
If you are a GitLab team member, request a review based on: - The documentation page's metadata.
- The associated Technical Writer.
If you are a GitLab team member and only adding documentation, do not add any of the following labels:
~"frontend"
~"backend"
~"type::bug"
~"database"
These labels cause the MR to be added to code verification QA issues.
Reviewer's checklist
Documentation-related MRs should be reviewed by a Technical Writer for a non-blocking review, based on Documentation Guidelines and the Style Guide.
If you aren't sure which tech writer to ask, use roulette or ask in the #docs Slack channel.
-
If the content requires it, ensure the information is reviewed by a subject matter expert. - Technical writer review items:
-
Ensure docs metadata is present and up-to-date. -
Ensure the appropriate labels are added to this MR. -
Ensure a release milestone is set. - If relevant to this MR, ensure content topic type principles are in use, including:
-
The headings should be something you'd do a Google search for. Instead of Default behavior
, say something likeDefault behavior when you close an issue
. -
The headings (other than the page title) should be active. Instead of Configuring GDK
, say something likeConfigure GDK
. -
Any task steps should be written as a numbered list. - If the content still needs to be edited for topic types, you can create a follow-up issue with the docs-technical-debt label.
