Hi thanks for your detailed log. What’s your sharding rule? Looking at log, i found the actual SQL is same with the logic one, and there is no difference. Does table named `cv_task_mark_user ` is a sharding table? Have you ever referred to sharding-examples[1], which provides several configuration examples for different situations ?
