Overview

Purging is performed automatically to improve performance.

You can set a purging policy that retains either a set number of pipeline runs, or all pipeline runs in a set number of days.

The purging policy applies to all space pipelines. You can also set a specific policy for a particular pipeline.

Purging affects the following historical pipeline data:

• Pipeline runs

• Automated test runs coming from pipeline runs

• Builds

The space admin can set the default purge policy for the space using the parameters in the table below.

At the space level, as an alternative to the parameters list, you can set the purge policy in a form. In the space, select More Settings > Purging.
