every hour's 7th minute, check if some task match:
(nextExecuteTime < now) && (endTime > now). if so, that means its a failed task for some reason. need retry, resend to MQ.

every hour's 37th minute, check if some task_execute_history match textContent is empty string or null, and group them by task id. if one taskId's histories textContent empty string or null > 5, send email to user.
