The __wt_heuristic_controls contains the following variables:
/* Number of btrees processed in the current checkpoint. */ wt_shared uint32_t obsolete_tw_btree_count; /* Maximum number of pages that can be processed per btree by checkpoint cleanup. */ uint32_t checkpoint_cleanup_obsolete_tw_pages_dirty_max; /* Maximum number of pages that can be processed per btree by eviction. */ uint32_t eviction_obsolete_tw_pages_dirty_max; /* Maximum number of btrees that can be processed per checkpoint. */ uint32_t obsolete_tw_btree_max;
This ticket should look into using __atomic_load and __atomic_store for those variables.
