# Architecture

- Infinite Polling With Events for De-Queue and En-Queue

- De-Queue

  - Every Dequeue sends a event to with the 'EventName' as the routing key

  - Consumers subscribe to the event associated with the routing key

  - Queue acquires a mutex lock , and waits for an event from a consumer which is sent to the queue once the message is consumed

  - Queue releases the mutex , de-queues and acquires the mutex once more

  - Producers push the message with a particular event name as the routing key

- En-Queue

  - Producer pushes the message with the particular event name as the routing key

- Dependency between Consumers

  - Consumers resolve the Dependency on a FIFO basis

  - Consumers can register dependencies and un-register at run-time
