Managing project history
One of the most powerful features of SonarQube Cloud is that it shows you not just the current state of your project health, but how project health has changed over time.
One of the most powerful features of SonarQube Cloud is that it shows you not just your project health today, but how it has changed over time. It does that by selectively keeping data from previous analyses (see the Housekeeping page). It doesn’t keep all previous analyses - that would bloat the database. Similarly, for the analyses it does keep, SonarQube Cloud doesn’t keep all the data. Once a project snapshot moves from the "last analysis", that is, the most recent, to being part of the project’s history, data below the project level is purged - again to keep from bloating the database.
Typically, these aren’t things you need to even think about; SonarQube Cloud just handles them for you, but occasionally, you may need to remove a bad snapshot from a project’s history or change the housekeeping algorithms.
Managing history
Occasionally, you may need to manually delete a project snapshot, whether because the wrong quality profile was used, or because there was a problem with analysis, and so on. Note that the most recent snapshot (labeled "last snapshot") can never be deleted.
Deleting snapshots
At the project level, from the front page Activity list, choose Show More to see the full activity list.
For every snapshot, it is possible to manually:
Add, rename or remove a version
Add, rename or remove an event
Delete the snapshot
