Push vs. Pull 作为一个messaging system,Kafka遵循了传统的方式,选择由producer向broker push消息并由consumer从broker pull消息。一些logging-centric system,比如Facebook的Scribe和Cloudera的Flume,采用非常不同的push模式。事实上,push模式和pull模式各有优劣。push模式很难适应消费速率不同的消费者,因为消息发送速率是...

Producer Throughput Vs. Stored Data 消息系统的一个潜在的危险是当数据能都存于内存时性能很好,但当数据量太大无法完全存于内存中时(然后很多消息系统都会删除已经被消费的数据,但当消费速度比生产速度慢时,仍会造成数据的堆积),数据会被转移到磁盘,从而使得吞吐率下降,这又反过来造成系统无法及时接收数据。这样就...

Cloud-native event integration In a decentralised architecture, Apache Kafka serves as an intermediary that connects different microservices. This solution gives you the option to create an event-driven architecture, which means your microservices get triggered by events in real time. SPECIFICATIONS Te...

For commands, which are typically business events that have a return value, there is a good argument for doing this in Kafka. The command is a business event and is typically something you want a record of. For queries it is different as there is little benefit to using a broker, there...
9.1.2.Implicit vs. explicit commands If behind every event is a command, how could we have reachedchapter 9in a book all about events without encountering a single command? The answer is that almost all software relies onimplicit commands—the decision to do something is immediately followed by...
