Kafka is only a small bond. It is often used for sending and transferring data. In the official case of Kafka, there is no relevant implementation version of PHP in fact. Now the online circulating Kafka of the relevant PHP library, are some of the programming enthusiasts write their own class library, so there will ce

Kafka is developed in the Scala language and runs on the JVM, so you'll need to install the JDK before installing Kafka. 1.

I recommend the second, because the Scala version and the Kafka version that are downloaded through Kafka compilation are matched (but sometimes may conflict with the environment that Eclipse's plugin needs, so it's best to install the first one, just in case), and generally we use a Java project to write, So

data to one or more Kafka topic2. The Customer API allows one app to subscribe to one or more topic and process the data streams that are produced to them3. Stream API allows applications like a stream processor to consume data streams from one or more topic inputs and then produce output data streams to one or more topic, efficiently converting between inputs and outputs4. The Connector API allows you to create and run reusable connections

to the network layer of the various anomalies. In a distributed system, the protocol is custom-made by the server, and the client can ensure that the client's request is received and processed gracefully as long as it follows the protocol to send the request. So in fact the implementation of the client can be implemented by different languages themselves, the official Wiki lists the majority of languages currently supported. Because of the different languages have their own network layer progra
