Reindexing

Starting SonarQube Community Build after an upgrade or after a restore from a backup triggers a rebuild of the Elasticsearch indexes. 

Project availability

Most features are available during reindexing (for example, you can already analyze your projects), but some only become available when the process is complete:

• Project issues and security hotspots: Available, but some filters and the ability to add tags become available only when reindexing is complete. 
• The global Issues page is unavailable until all projects are reindexed.

SonarQube Community Build uses analysis dates to determine which projects to prioritize during reindexing. Your projects with the most recent analysis dates are the first to become fully available in the UI.

Administrators can track the full reindexing progress:

• Within the banner displayed in SonarQube Community Build.
• In the background tasks.

Running analyses during reindexing

Reindexing starts once SonarQube Community Build is up and running. You can run analyses on your projects on the CI side while indexes are being rebuilt. The processing of analysis results takes priority over reindexing tasks, so your SonarQube Community Build instance is effectively operational.

Administrators can check the progress of these analyses in Administration > Projects > Background tasks.

Quality gate timeout

When calculating the quality gate of a project that is actively being indexed, SonarQube Community Build will finish indexing to allow computation to complete before returning quality gate status. If the indexing does not finish by the Quality Gate timeout setting, then the Quality Gate will time out.

Forcing an Elasticsearch reindex

You can trigger a full Elasticsearch reindex. During the reindex, SonarQube will detect out-of-sync indices and correct them.

Proceed as follows:

1. Stop the server.
2. Remove the contents of the <sonarqubeHome>/data/es8 directory where <sonarqubeHome>:
   • For a ZIP installation: is the location where the SonarQube distribution has been unzipped.
   • For a Docker installation: is the installation directory of SonarQube within your container. This path is stored in the SONARQUBE_HOME environment variable. 
3. Start the server.

Reindexing a single project

You may have to reindex a project if it shows inconsistent data or fails to reindex after an instance version upgrade or during a forced ElasticSearch reindex. To perform this procedure, you need the Administer System permission.

To reindex a single project:

• Use the SonarQube Server Web API api/issues/reindex.
