GitLab application limits

GitLab, like most large applications, enforces limits within certain features to maintain a minimum quality of performance. Allowing some features to be limitless could affect security, performance, data, or could even exhaust the allocated resources for the application.

Number of comments per issue, merge request or commit

Introduced in GitLab 12.4.

There's a limit to the number of comments that can be submitted on an issue, merge request, or commit. When the limit is reached, system notes can still be added so that the history of events is not lost, but user-submitted comments will fail.

Max limit: 5.000 comments

Number of pipelines per Git push

Introduced in GitLab 11.10.

The number of pipelines that can be created in a single push is 4. This is to prevent the accidental creation of pipelines when git push --all or git push --mirror is used.

Retention of activity history

Introduced in GitLab 8.12.

Activity history for projects and individuals' profiles was limited to one year until GitLab 11.4 when it was extended to two years, and in GitLab 12.4 to three years.

Number of project webhooks

Introduced in GitLab 12.6.

A maximum number of project webhooks applies to each GitLab.com tier. Check the Maximum number of webhooks (per tier) section in the Webhooks page.
