Repository update frequency
By default, Sourcegraph polls code hosts to keep repository contents up to date, effectively running
git pull periodically. You can also configure Sourcegraph to use repository webhooks, but this is usually not necessary.
The frequency at which Sourcegraph polls the code host for updates is determined by a smart heuristic based on past commit frequency in the repository. For example, if a repository’s last commit was 8 hours ago, then the next sync will be scheduled 4 hours from now. If after 4 hours, there are still no new commits, then the next sync will be scheduled 6 hours from then.
Repositories will never be updated more frequently than 45 seconds, and no less frequently than every 8 hours.
After Sourcegraph has updated a repository’s Git data, the global search index will automatically update a short while after (usually a few minutes).
Limiting repository updates
If you wish to control how frequently repositories are discovered or how frequently Sourcegraph polls your code host for updates, tuning parameters are available in the site configuration:
- repoListUpdateInterval controls how frequently we check the code host for new repositories in minutes.
- gitMaxConcurrentClones controls the maximum number of concurrent cloning / pulling operations per gitserver that Sourcegraph will perform.
You may also choose to disable automatic Git updates entirely and instead configure repository webhooks.
Code host API rate limiting
NOTE Internal rate limiting is currently only enforced for syncing changesets in batch changes, repository permissions and repository metadata from code hosts.
Repo Updater State
Repo Updater State is a useful debugging tool for site admins to monitor:
- Schedule: The schedule of when repositories get enqueued into the Update Queue.
- Update Queue: A priority queue of repositories to update. A worker continuously dequeues them and sends updates to gitserver.
- Sync jobs: The current list of external service sync jobs, ordered by start date descending
Site admin: Go to Site admin > Instrumentation (under Maintenance) > repo-updater > Repo Updater State
