<div dir="ltr">hello everyone,<div> I am a new beginner of Rabbitmq. I am fascinated by its efficiency and easy to use. But I have some problem and want to ask every engineer.</div><div>1.what is rabbitmq-server's default TTL time? I didn't configure any data to rabbitmq.</div>
<div>2.what kind of data structure and which type of data can be delivered to rabbitmq-server? </div><div>3.If I didn't want to lose any message , how can I design our message queue architecture. I know that rabbitmq has durable parameter solution but it still can't guarantee it didn't lose any message at all, especially for the data stored in memory but not in the disk. I also know that durable solution and transaction method will effect qps performance greatly, Can you help to design a good message queue system using rabbitmq and don't lose any message?</div>
<div>4. Can you give me a demo code about how to use transaction of rabbitmq in java or python?</div><div> thank you very much ~~</div></div>
