Apache Kafka
In plain terms
A distributed platform for high-throughput event streaming.
Going deeper
Kafka stores and processes streams of events durably across a cluster, enabling real-time pipelines and event-driven systems at scale. It's the backbone of many data pipelines.
Under the hood
Append-only partitioned logs with consumer groups give scalable, replayable streams; not a simple queue.
Examples
Event streaming, log pipelines, real-time analytics, microservice events, CDC.
Think of it like...
Like a massive, durable conveyor belt of events that many systems read from independently.
