Kafka

Apache Kafka is a distributed streaming platform that is used for building real-time data pipelines and streaming applications. It is designed to handle high volumes of data with low latency, and it is often used to process and transmit large amounts of data between systems in near-real time.

In a Kafka system, data is organized into topics, and producers write data to topics while consumers read data from topics. Kafka stores all published messages for a configurable amount of time, allowing consumers to read data at their own pace and enabling real-time data processing.

Kafka is highly scalable and fault-tolerant, and it can handle millions of messages per second. It is also highly configurable, and it provides a number of features for managing data streams, including the ability to partition data, replicate data across multiple servers, and configure retention policies for data.
