Kafka now enables transactional writes, which use the Streams API to deliver exactly-once stream processing, starting with the 0.11.0.0 release. by allowing it to deliver enormous streams of messages in a fault-tolerant manner. This architecture enables Kafka to replace some of the traditional messaging systems like Java Message Service (JMS), Advanced Message Queuing Protocol (AMQP), etc. Partitions are also copied across numerous brokers. The partitions of all topics are distributed throughout the cluster nodes, and Kafka runs on a cluster of one or more servers (referred to as brokers).
Other external stream processing platforms including Apache Apex, Apache Beam, Apache Flink, Apache Spark, Apache Storm, and Apache NiFi can be used in conjunction with Apache Kafka. Kafka provides the Streams API for stream processing, enabling developers to create Java programs that read data from Kafka and return results to Kafka. Partition messages can be read by “consumers,” or other processes. The data can be divided up into many “partitions” inside various “themes.” Messages are indexed and saved combined with a date and rigorously arranged inside a partition according to their offsets (the position of a message within a partition). Key-value messages that originate from arbitrary numbers of processes known as producers are stored in Kafka. In addition, cloud providers don’t generally make their products interoperable. With many large enterprises moving toward multi-cloud environments and hybrid cloud deployments, it is crucial for companies to standardize their real-time streaming data infrastructure stack. However, with increasing competition from cloud providers and emerging open source projects, Confluent has a distinct advantage. Today, Kafka-based streaming data solutions are available through cloud providers, and Apache Kafka is the most popular open source solution. While Kafka has grown rapidly over the last decade, the platform’s developers and community have been working to make it more user-friendly.
Because of the larger network packets, larger sequential disk operations, and contiguous memory blocks that result from this, Kafka is able to convert a bursty stream of errant message writes into linear writes. Kafka relies on a “message set” abstraction, which naturally groups messages together to lessen the overhead of the network roundtrip, and uses a binary TCP-based protocol that is optimized for efficiency. The Kafka Streams libraries are available for stream processing applications, and Kafka can connect to external systems (for data import/export) via Kafka Connect. A unified, high-throughput, low-latency platform for handling real-time data feeds is what the project seeks to provide.
