## Context This is the first step in kicking off https://gitlab.com/groups/gitlab-org/-/work_items/20250. ## Goal Identify opportunities to improve the performance of this worker. This will serve as the basis to create an implementation plan. ## Proposal This is a spike and up to the assignee to define the approach. Some ideas: - Inspect latest performance data to detect patterns. - Understand what these customers (the top outliers causing most apdex problems) are trying to achieve. - Add timing logging to confirm where the bottlenecks are. - Connect with experts for any specialized input needed (e.g. database). - Identify if different API restrictions should be put in place. - Example: https://gitlab.com/gitlab-org/gitlab/-/work_items/585176 - Consult with ~"devops::plan" on their traversal ID effort, which solves a similar problem for work items. - https://handbook.gitlab.com/handbook/engineering/architecture/design-documents/traversal_ids_on_issues/ - https://gitlab.com/groups/gitlab-org/-/work_items/18644 - ... ## Links - Previous research: https://gitlab.com/gitlab-org/gitlab/-/work_items/552376 - Dashboard: https://log.gprd.gitlab.net/app/r/s/tkljo
