Issue Summary
When Jira serializes issue payloads for webhooks, the process of including changelog items suffers from an N+1 query problem.
For issues with a large number of changelog entries, Jira fetches metadata for each changelog in a separate database query, sometimes with additional queries for permission checks, resulting in significant performance degradation.
Steps to Reproduce
1. Create an issue and perform a large number of updates to generate a substantial changelog history.
2. Trigger a webhook (e.g., issue updated).
3. Observe the time taken to generate and deliver the webhook payload.
Expected Results
Webhook payloads are generated efficiently, with changelog items fetched in a performant, batched manner.
Actual Results
Webhook payload generation is slow. Profiling shows that fetching changelog metadata dominates serialization time due to N+1 queries, for example:
