original solution, the broker's fail will cause data loss. It is a bit too difficult to say, so the replica feature is necessary. 2. Logic offset is used. The advantages mentioned above are described. However, when physical offset is used, a bunch of advantages are also described.In fact, it is the balance of efficiency and ease of use. Previously, for the pursuit of efficiency, we used physical offset.Now, considering that physical offset is too difficult to use, we have to make a compromise a

Kafka is a distributed publish-subscribe messaging system, which is simply a message queue, and the benefit is that the data is persisted to disk (the focus of this article is not to introduce Kafka, not much to say). Kafka usage scenarios are still relatively large, such as buffer queues between asynchronous systems, and in many scenarios we will design as follo

To demonstrate the effect of the cluster, a virtual machine (window 7) is prepared, and a single IP multi-node zookeeper cluster is built in the virtual machine (the same is true for multiple IP nodes), and Kafka is installed in both native (Win 7) and virtual machines.Pre-preparation instructions:1. Three zookeeper servers, the local installation of one as Server1, virtual machine installation two (single IP)2. Three

Kafka introduction, Kafka is useful for building real-time data pipelines and stream applications. Apache Kafka is a distributed stream platform. What does this mean? We consider that the middleware has three key capabilities: What is the use of Kafa? It is used for two types of applications: So how does Kafka impleme

This article will show you how to build the Kafka environment, and we'll start with a standalone version and then gradually expand to distributed.

1 overview KAKFA was originally a distributed messaging system developed by LinkedIn and later became part of Apache, which was written in Scala and is widely used for horizontal scaling and high throughput rates. At present, more and more open-source distributed processing systems such as Cloudera, Apache Storm, Spark and so on are supporting integration with Kafka. Kafka by virtue of its own advantages,
