This ticket aims to investigate and (if exists) address the issue of pages with many updates not being queued in the eviction process. Despite reaching target trigger levels, the eviction server fails to populate the eviction queue with these pages, resulting in performance degradation and application thread stalls. See the related help tickets.
Goals:
- Investigate and replicate a scenario where clean and dirty pages are evicted, but the eviction server fails to queue pages with many updates.
- Determine the underlying reason behind the eviction server's inability to queue these pages.
Outcome:
By investigating and addressing the eviction server's inability to queue pages with many updates, we aim to optimize the eviction process, prevent latency increase, and eliminate application thread stalls. This investigation (hopefully) will lead to stability in scenarios involving high update activity.
