双写期存在“主库写成功、补偿未落库”宕机窗口
node 双写期是 Heavy 主路径,Default 副路径。
如果 Heavy 写成功后,进程在写 Default 或记录补偿任务前宕机,可能出现 Heavy 有、Default 没有、补偿队列也没有记录。后续只能靠对账发现,补偿队列本身兜不住这个窗口。
VERIFY 的自动修复能力不完整
当前少量分片不一致时会重新从 Default 扫描并 upsert 到 Heavy。
这能修“缺失/旧版本”,但不能清理 Heavy 多出来的僵尸数据。如果不一致原因是 Heavy 多数据,单纯 upsert 不会解决,可能反复 VERIFY 或最终进入 REBUILD_REQUIRED。
