Eviction verbose logging category analysis:
A detailed analysis of eviction-related logging messages has revealed three distinct categories:
- WT_VERB_EVICT: Used in multiple scenarios, including long eviction times, individual page evictions, and page marking for reconciliation.
- WT_VERB_EVICT_STUCK: Currently unused within the WiredTiger codebase.
- WT_VERB_EVICTSERVER: Used in multiple instances.
Proposed Simplification:
To streamline the eviction logging and enhance readability, I recommend consolidating all eviction-related messages under a single category, WT_VERB_EVICT. This unified approach will reduce complexity and improve maintainability.
Next Steps:
Review the code using all three categories and consolidate it under one category, WT_VERB_EVICTION.
By following these steps, we can effectively simplify the eviction verbose messaging system and improve code clarity.
