The use of message brokers allows you to ensure fast communication between components of distributed systems, simplify scaling. There are several types of brokers focused on specific tasks. In particular, for publish or subscribe messaging systems, data processing speed is critical, requiring a broker with the appropriate characteristics. Apache Kafka most fully meets the specified and some other criteria, which made it quite popular in the specified segment. We will consider the technical possibilities and demonstrate working with it in practice.
What is a message broker? This is a software module that Armenia Telemarketing Data performs mediating functions in communications between components of distributed systems. The main elements of any broker are the issuer of messages and their recipient or subscriber. The broker determines the protocol of interaction between them, that is, establishes rules that, in particular, regulate the sequence and time of message formation, the time of their storage on the server, and some others. Brokers allow you to organize asynchronous mode of data exchange and can be useful in the following cases: To implement deferred execution of actions; Smoothing of peak loads; Sending a large number of messages; Implementation of complex business logic of distributed systems; Ensuring data persistence; Organization of tasks according to the schedule.
The most popular brokers, besides Apache Kafka, are RabbitMQ and Redis, each of which is focused on a specific use. Features of Apache Kafka The software tool is one of the fastest among the existing brokers, the speed of processing messages is about 1 million per second. In addition, the following features can be distinguished: Automatic notification of customers (subscribers) about the availability of messages; Generating an "unlimited" number of messages; Ensuring data persistence – the ability to update or read messages later; Guaranteeing a clear sequence of receiving messages by subscribers within topics. The specified features of the program allow it to occupy the first positions when used in publishing or subscription systems, which was already discussed above.
