So I can remove DB and send data to RabbitMQ queue? How does that work with e.g. bulk of 500+ MB data? For this big data, do I send them in json format? Thanks

Nice concept, but I did not get the exact point here. Is the benefit in not using a database at all or in the consuming vs polling process? Because the consumer process also will be asking the queue for the message in some time intervals just like the background job will be polling the database for data in some time intervals. Just like the consumer, the background job will also not be required to be running every time. So whats the benefit here?

A message comin in the queue, won't the worker also keep polling the queue behind the scenes technically to fetch the message?
