@mattisonchao Thank you for your help, the official document has too little introduction to the delay message, I would like to ask the next few questions
1. Does every subscription broker maintain a delayed index?
2. Is there a limit to the size of the delayed index?
3. After the message expires, is the message transferred from the temporary storage space to the persistent storage for consumers to consume?
