RabbitMQ can scale up to around 50,000 messages per second.
It is less than Apache Kafka and Redis Pub/Sub. But there are some advantages of rabbitMQ over these two.
You can’t schedule messages in Apache Kafka and Redis Pub/Sub.

Queue binds to the exchange.

There are various types of exchange types.
- Direct Exchange: A direct exchange delivers messages to queues based on the message routing key.
