Multiple nodes: multiple broker clusters.A single node: multiple broker clusters.

we can create multiple types of clusters, such as the following: A Kafka broker allows consumers to fetch messages by a topic, partition, and offset. A Kafka broker receives messages from producers and stores them on a disk. Each partition can be hosted on a different server, which means that a single topic can be scaled horizontally across multiple servers to provide performance far beyond the ability of a single server.īrokers and Clusters: A Kafka cluster consists of one or more servers and each single Kafka server is called a broker. Partitions allow topics to be parallelized by splitting the data into a particular topic across multiple brokers. Messages are written to it in an append-only fashion and are read in order from beginning to end. Topics are broken down into a number of partitions. The advanced clients use producers and consumers as building blocks and provide higher-level functionality on top. There are also advanced client APIsKafka Connect API for data integration and Kafka Streams for stream processing. Producer and Consumer: Kafka clients are users of the system, and there are two basic types producers and consumers. There are many options available for message schema, depending on the application’s individual needs Like JSON or XML are easy to use and human-readable. Schemas: A consistent data format is important in Kafka, as it allows writing and reading messages to be decoupled. The larger the batches, the more messages that can be handled per unit of time, but the longer it takes an individual message to propagate. A batch is just a collection of messages, all of which are being produced to the same topic and partition. A message can have an optional bit of metadata, which is referred to as a key.įor efficiency, messages are written into Kafka in batches. A message is simply an array of bytes, so the data contained within it does not have a specific format or meaning to Kafka. The closest analogies for the message are a row or a record. Messages and Batches: The unit of data within Kafka is called a message. These are the main parts of a Kafka system: It combines messaging, storage, and stream processing to allow storage and analysis of both historical and real-time data. Kafka is primarily used to build real-time streaming data pipelines and applications that adapt to the data streams. Process streams of records in real-time.Effectively store streams of records in the order in which records were generated.Publish and subscribe to streams of records, similar to a message queue or enterprise messaging system.Today data and logs produced by any source are being processed, reprocessed, analyzed, and handled in real-time and that’s why Apache Kafka is playing a significant role in data streaming.

Kafka is open-source software that provides a framework for storing, reading, and analyzing a stream of data. We take information in, analyze it, manipulate it, and create more as output. Every application creates data, whether it is log messages, metrics, user activity, outgoing messages, or whatnot. Today almost every enterprise is powered by data.
