目的
It's very common to look for ticket outliers that can impact system performance such as issues with thousands of links or comments that might've been added by faulty automation or simply kept growing overtime. It is not unusual for issues with lots of associated links or comments cause threads to hang or connection to timeout before all the data is fetched.
ソリューション
We recommend testing these queries in your staging environment. They were created on PostgreSQL and may need tuning depending on your database. These will help you to identify issues that can be expensive when fetching their information from the database, so you can review them and potentially take actions to remediate the problem (e.g. deleting or archiving those issues, deleting excessive comments, links or attachments).
