Task scheduling: Delayed queues can be used to create timed task schedules, allowing tasks to be executed after a specified delay time.
Cache expiration: A delay queue can be used to handle cache expiration issues, for example setting an expiration time in the cache and removing data from the cache when it expires.
Message retry: Delayed queues can be used to handle message retry mechanisms, for example, if a message fails to be consumed, it can be placed back into a delayed queue and attempted to be consumed again after a certain period of time.
Rate limiting: Delay queue can be utilized for traffic control, such as setting a fixed time interval where operations can only proceed after the interval has elapsed.
Timeout handling: Delayed queues can be used to address timeout issues, for example by setting a timeout when waiting for a response result, and handling a timeout exception when it occurs.
