Kafka uses an offset to bookmark a consumer’s progress in processing data, so if the service fails it can easily come back to where it left off without duplicating any effort. As a consumer reads messages and the offset moves, older, read messages are persisted to disk for later analysis...
The Kafka service port can able to utilizes the Kafka service on the Kafka server using 9092 as a default port in which it can have communication through TCP as it is beneficial to implement the lamina in a hybrid cloud environment, the data flowing service can have more rigid requirements t...
kafka并没有提供其他额外的索引机制来存储offset,因为在kafka中几乎不允许对消息进行“随机读写”。 对于consumer而言,它需要保存消费消息的offset,对于offset的保存和使用,有consumer来控制;当consumer正常消费消息时,offset将会"线性"的向前驱动,即消息将依次顺序被消费.事实上consumer可以使用任意顺序消费消息,它只需要将...
We can say that the Kafka rebalancing is the process of plotting the partitions to consumers in a specific manner, when rebalancing is going on then one partition can be handed over to the consumer in an incremental way, let us understand it with the help of the following figure, From the...
and commit the messages to disk storage. An offset is a unique integer value that Kafka increments and adds to each message as it’s generated. Offsets are critical for maintaining data consistency in the event of a failure or outage, as consumers use offsets to return to the last-consumed...
Kafka topics are divided into a number of partitions, which contain records in an unchangeable sequence. Partitions allow topics to be parallelized by splitting the data into a particular topic across multiple brokers. Offset: Each record in a partition is assigned and identified by its unique off...

In contrast to Apache Kafka, RabbitMQ is an oldie, as it was built in 2007. RabbitMQ was a major component in SOA systems. However, nowadays it is being used for streaming purposes as well. Now let’s try to understand the architecture of these two products. ...
In general, ZooKeeper provides an in-sync view of the Kafka cluster. Kafka, on the other hand, is dedicated to handling the actual connections from the clients (producers and consumers) as well as managing the topic logs, topic log partitions, consumer groups ,and individual offsets. ...
