要約

For large or Data Center instances you should suspect there are alot of open pull requests that have not been updated in a while and are still open.  In a large Bitbucket Data Center environment this can add up to be a large number.  Each time the repository is updated, each open pull request needs to be evaluated to see if it needs to be updated.  This can add to the background load.  Closing out old open pull request can improve Bitbucket Data Center performance.

Having a small set of open pull request on a repository is normal.  It is not abnormal to have 50 to 100 open pull requests for a repository.

診断

This SQL will show you all of the pull request that have had 1000+ rescopes and the last time the pull request was updated.  This can indicate the age of the pull request.  You can change the value to 500 or 100 to see how extensive the problem is on Bitbucket by changing the value:  pr.entity_version > 1000 ← Here.

SELECT p.project_key, 
       r.slug, 
       pr.scoped_id, 
       pr.entity_version, 
       pr.updated_timestamp 
FROM   sta_pull_request pr 
       JOIN repository r 
         ON pr.to_repository_id = r.id 
       JOIN project p 
         ON r.project_id = p.id 
WHERE  pr.pr_state = 0 
       AND pr.entity_version > 1000 
ORDER BY pr.entity_version desc;

This SQL will groups the pull request by project so you can isolate a particularly problematic project.

SELECT p.project_key, 
       Count(1) 
FROM   sta_pull_request pr 
       JOIN repository r 
         ON pr.to_repository_id = r.id 
       JOIN project p 
         ON r.project_id = p.id 
WHERE  pr.pr_state = 0 
       AND pr.entity_version > 1000 
GROUP  BY p.project_key
ORDER BY 2 desc; 

原因

Sometimes pull request do take an extended period of time to evaluate if they need to be merged.  But sometimes pull request get lost in the shuffle.  Remember open pull request might be needed.  Except for only the most obvious of cases, Only a developer of the code can know if the pull request should be closed.

ソリューション

Request that the owners of the repository close some of the older pull requests.
