Method 1:
You can consider triggering a scheduled cleanup operation when inserting a new order. Specifically, read the last order cleanup time, and then compare it with the current system time. If the scheduled cleanup is exceeded, time (for example, 30 minutes), perform a cleanup operation and delete expired orders in the order table.
These configuration data can be saved in the system configuration table, such as:
conf(conf_name, conf_value)order_last_clean_time: 1493101925
(Last order cleaning time)
order_cron_clean_time: 30 minutes
(Duration of scheduled cleaning)
order_expire_time: 30 minutes
(Orders that have not been paid for more than 30 minutes are considered expired)
