Push Vs Pull

Pull base

• Pull is better when dealing with diversified consumers.
• Pull consumer can effectively control its own rate of consuming
• Easier and more optimal for batch processing
• Pull consumer no need to keep the connection
• Draw back: keep polling when there is no data.
  • We can introduce long-polling waiting mode until data arrives

Push base

• Need to keep the connection
• have different push types
• harder to scale

For pull-based: Kafka
For push-based: RabbitMQ
